V
Vir +
418,12
Example 8.12: Two charged particles
having equal charge of 3 x10-5 C each are
brought from infinity to a separation of
30 cm. Find the increase in electrostatic
potential energy during the process.
Solution : Taking the potential energy (PE)
at oo to be zero,​

Answer 1

p.E= k q1q2/r .......1

where k= 9×10^9

so put in eq 1

p.E=9×10^9 (3×10^-5)^2/0.3

u will get ans
