In the figure shown, conducting shells A and B have charges Q and 2Q distributed uniformly over and B. Value of `V_(A) - V_(B)` k is `(kQ)/(nR)`. Find `n ( k = (1)/(4 pi in_(0))`

Text Solution

Verified by Experts

The correct Answer is:
A, B
`V_A=1/(4 pi e_0) [Q/(3R)+(2Q)/(4R)] , V_B=1/(4 pi e_0) (3Q)/(4R), V_A- V_B=(kQ)/(12R)`

Figure shows two rings having charges Q and - sqrt(5)Q . Find potential difference a and B i.e. (V_(A)-V_(B)) .

Assertion : Two concentric spherical shells A and B are charged by charges q_(A) and q_(B) . If q_(A) is negative, then V_(A)-V_(B) is also negative. Reason : V_(A)-V_(B) =(q_(A)/(4pi epsi_(0)))(1/R_(A)-1/r_(B)) therefore, if q_(A) is negative, then V_(A)-V_(B) is also negative.
