Question

Two point charges of +10 microfarad and -10microferred are separated by distance of 40 cm in air.calculate the electrostatic potential energy of ths system,assuming the zero of the potential energy to the infinity solution.

Answer 1

electro static potential will be zero because V=k( 10×
${10}^{ - 6}$
÷40×
${10}^{ - 4}$
-10×
${10}^{ - 6}$
÷40×
${10}^{ - 4}$
)=0
