Question:

The force between two charged spheres with charges q1 = 2C and q2 = -1C is 64N. If these spheres are brought in contact and separated, then new force will be.

_______________________________

Solution:

According to the given condition

» F = 9 × 10⁹ × (q1 q2) / r²

» 64 = 9 × 10⁹ × (2) / r²

» r² = (9 × 10⁹ × 2) / 64

After bringing spheres in contact, each charge will have half of the net charge.

Net charge = 2 - 1 = 1 C

Therefore, each sphere will have charge of ½ C.

Now, F = (9 × 10⁹ × (½)²) / r²

» F = (9 × 10⁹ × 64) / (9 × 10⁹ × 4 × 2)

» F = 8 N

Therefore, the force will be of 8 N between the spheres.
