Question

Find charge on capacitors C, if a battery of e.m.f. E is connected across face diagonal of a cube as shown in figure. Resistance of each branch (except the branch which contains capacitor) of cube = R

(A) CE 

(B) 2CE 

(C) CE/2 

(D) zero

Answer 1

Correct option (D) zero

Explanation: 

Due to symmetry of circuit, no current will flow in branches having capacitors. So charges on capacitors ≡ zero.
