what is electrostatic potential energy of a charged sphere with radius R?
If R is the Radius and Charge is q, then the electric potential is calculated using the formula:
E =1/2(/4 π 01. Q 2/R)
1/8 K Q2/R (1 /π 01= K )
The numerator and denominator might not be shown clearly here because of the formula structure. So we would suggest you to refer NCERT Books for the same.
