JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

Two similarly equally charged identical metal spheres

A

and

B

repel each other with a force of

2.0 \times 10^{-5} \mathrm{~N}

.

A

third identical uncharged sphere

C

is touched to

A

, then placed at the midpoint between

A

and

B

. Calculate the net electrostatic force on

C

.

View answer and explanation

Correct option: B

2.0 \times 10^{-5} \mathrm{~N}

Option B (

2.0 \times 10^{-5} \mathrm{~N}

) is correct because it is the net electrostatic force on sphere C, calculated by considering the forces due to spheres A and B.
