Question

+2 C and +6 C two charges are repelling each other with a force of 12 N. If each charge is given -2 C of charge, then the value of the force will be ______

पर्याय

• 4 N (Attractive)

• 4 N (Repulsive)

• 8 N (Repulsive)

• Zero

Answer 1

+2 C and +6 C two charges are repelling each other with a force of 12 N. If each charge is given -2 C of charge, then the value of the force will be Zero.

Explanation:

Resultant charges after adding the -2 C be (-2 + 2) = 0 and (-2 + 6) = + 4 C

∴ F = `("k""q"_1"q"_2)/"r"^2 = "k" xx (0 xx 4)/"r"^2 = 0`
