Conducting shell of radius R carrying charge Q , another charge Q is placed at 3 R distance from centre of shell. If the potential at point P due to charge on shell is 11 3 n K Q R , Then the value of n is

Correct answer

5

Step-by-step solution

aligned & V_O=V_P & K Q R + K Q 3 R =V_ shell + 2 K q 5 R & V_ shell = K Q R [1+ 1 3 - 2 5 ] & = K Q R [ 4 3 - 2 5 ] & = K Q R [ 20-9 15 ]= 11 15 K Q R aligned
