Two trains 132 m and 108 m long are running in opposite directions with speeds of 32 km/h and 40 km/h respectively. How long will it take them to cross each other after meeting?
Detailed Solution for MPPGCL JE Electrical Mock Test - 2 - Question 6

Given:

Speed of train1 = 32 km/h

Speed of train2 = 40 km/h

Length of train1 = 132 m

Length of train2 = 108 m

Formula used:

If bodies moving in opposite direction = (x + y) km/h

If bodies moving in same direction = (x – y) km/h

Speed = Distance/Time

1 km/h = (5/18) m/sec

Calculation:

The sum of the length of the train = (132 + 108) m

⇒ 240m

According to the question

Relative speed = (32 + 40) km/h

⇒ 72 km/h

⇒ (72 × 5/18) m/sec = 20 m/sec

Now,

Time taken = Total distance/Speed

⇒ (240/20) sec

⇒ 12 sec

∴ Required time is 12 sec

Direction: Study the following information carefully and answer the given questions besides.

M, N, O, P, Q, R, S and T are sitting around a circular table and all are facing the centre of the table. M is sitting fourth to the right of N. P is sitting second to the left of N. Q is sitting third to the right of S. T is sitting second to the left of O. S is not sitting beside P. O is not sitting beside M.
Q. Who among the following sits exactly opposite to Q?
Detailed Solution for MPPGCL JE Electrical Mock Test - 2 - Question 10

From the common explanation, we get O sits exactly opposite to Q.

Hence, Option B is correct.

Final Arrangement:

Common Explanation:

References:

M is sitting fourth to the right of N.

P is sitting second to the left of N.

Inferences:

From the above reference, we get the following arrangements:


References:

Q is sitting third to the right of S.

Inferences:

From the above reference, we get two different cases:

Case 1:


Case 2:


References:

S is not sitting beside P.

T is sitting second to the left of O.

O is not sitting beside M.

Inferences:

So, from this case 1 will be eliminated as S is not sitting beside P.

Thus, the final arrangement,

Which of the following is true with respect to Schottky diode?
Detailed Solution for MPPGCL JE Electrical Mock Test - 2 - Question 11

The Schottky also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. A silicon diode has a typical forward voltage of 600–700 mV, while the Schottky's forward voltage is 150–450 mV. This lower forward voltage requirement allows higher switching speeds and better system efficiency.

A certain R-L series combination is connected across a 50 Hz single-phase ac supply. If the instantaneous power drawn was found to be negative for 2 milliseconds in one cycle. The power factor angle of the circuit must be____
Detailed Solution for MPPGCL JE Electrical Mock Test - 2 - Question 18
RL series circuit is an inductive circuit. Voltage leads the current. The instantaneous voltage and current can then be expressed as

The instantaneous power can be obtained by multiplying the two. P =vi.

It can be seen from the diagram that in the angle interval 0 to ϕ, the voltage is positive but the current is negative and hence the power is negative. Similarly, in the angle interval π to π+ϕ the voltage is negative but the current is positive and hence the power is again negative.

In other regions the power is positive. Now we just have to find what time interval corresponds to phase difference ϕ. For this we use the formula,

entering the circuit is-
Detailed Solution for MPPGCL JE Electrical Mock Test - 2 - Question 21

Given-

Since 6 Ω and 8 Ω resistors are connected in parallel, therefore the voltage across them is the same i.e. 48 V.

Current through 6 Ω resistor = 48/6 A

= 8 A

Current through 8 Ω resistor = 48/8 A

= 6 A

Total current entering the circuit i = (8+6) A

i = 14 A

Hence, the correct option is (C).
