1 of 1

Application +4 | -1

Two insulated charged metallic spheres

P

and

Q

have their centres separated by a distance of

50 \mathrm{~cm}

. The radii of

P

and

Q

are negligible compared to the distance of separation. The mutual force of electrostatic repulsion if the charge on each is

3.2 \times 10^{-7} \mathrm{C}

is:

View answer and explanation

Correct option: A

3.69 \times 10^{-3} \mathrm{~N}

Option A (

3.69 \times 10^{-3} \mathrm{~N}

) is correct because it calculates the electrostatic force using Coulomb's law with the given charges and separation distance.
