The arithmetic mean between a and 10 is 30, the value of ‘a&rsqu...
A is -10.

We can solve for a using the formula for the arithmetic mean:

(mean) = (a + 10) / 2

Substituting the given values:

30 = (a + 10) / 2

Multiplying both sides by 2:

60 = a + 10

Subtracting 10 from both sides:

50 = a

Therefore, the value of a is -10.

Question No. 40 and 41 are based on the following paragraph.Consider a block of conducting material of resistivity ‘ρ’ shown in the figure. Current ‘I’ enters at ‘A’ and leaves from ‘D’. We apply superposition principle to find voltage ‘ΔV’ developed between ‘B’ and ‘C’. The calculation is done in the following steps:(i) Take current ‘I’ entering from ‘A’ and assume it to spread over a hemispherical surface in the block.(ii) Calculate field E(r) at distance ‘r’ from A by using Ohm’s law E =ρj, where j is the current per unit area at ‘r’.(iii) From the ‘r ’ dependence of E(r), obtain the potential V(r) at r.(iv) Repeat (i), (ii) and (iii) for current ‘I’ leaving ‘D’ and superpose results for ‘A’ and ‘D’.Q.40.ΔV measured between B and C is
