The shadow of a building is 10 m long when the point of rise of the sun is 60°. Discover the building's stature.

Detailed Solution for MPPGCL JE Electrical Mock Test - 3 - Question 1


Let AB be the building and AC be its shadow.
Then, AC = 20m and ∠ACB = 60°. Let AB = x m.
Presently AB/AC = tan 60° = √3 => x/10 = √3
=> x = 10√3m = (10 * 1.732) m = 17.32m.
∴ Height of the building is 17.32m.

Statement I: A sits to the immediate left of C. D sits second to the right of A.
Statement II: D sits immediately between E and B. B sits to the immediate left of A.
Detailed Solution for MPPGCL JE Electrical Mock Test - 3 - Question 11

From Statement 1:
A sits to the immediate left of C.
D sits second to the right of A.

From the statement, we cannot determine who sits second to the right of B.

Which of the following is the protective device against lightning overvoltages ?
Detailed Solution for MPPGCL JE Electrical Mock Test - 3 - Question 19
In high voltage power systems, insulation coordination studies are needed in order to minimize the probability of equipment failure due to the lightning or switching surges hazards. Proper surge arresters, as well as installation of other mitigation devices, are essential from the point of view of reliable working conditions of the transmission and distribution networks. It is difficult to measure such overvoltages due to operational, technological and economic issues. However, over the years reliable methods of computational analyses have been developed, which allow one to determine possible overvoltage waveforms for different scenario, including lightning surges or transformer switching operations.
