Two charged particles having charge 2.0 × 10 –8 C each are joined by an insulating string of length 1m and the system is kept on a smooth horizontal table. Find the tension in the string.

Question

Philoid · Accepted Answer

Given,

Charge on each particle,

Distance between the two charges,

The tension will adjust such that the net force is zero.

__________________________________________________

Formula used:

By Coulomb’s law, the electric force id given by:

Where ϵ₀ is the permittivity of free space

q₁ and q₂ are the magnitude of charges

r is the distance of separation between the charges

(Here, q₁ =q₂ = q.)

Putting the values in the above formula, we get

Two charged particles having charge 2.0 × 10–8 C each are joined by an insulating string of length 1m and the system is kept on a smooth horizontal table. Find the tension in the string.
