# Tension in a charged ring.

A ring is positively charge with uniform linear charge density $$\lambda$$ and radius $$r$$ , now a positive charge $$q_0$$ is placed at the center of the ring in the same plane.

Find the total tension after $$q_0$$ is placed.

Permitivity of free space is $$\epsilon _0$$.

Hint: There will be tension due to two.

yes , tanishq's answer is absolutely correct ! ( i guess so )

I guess this is the answer.. T=kQq / 2.pi.R^2 But can you solve it and show..

Is it correct

$$T=\frac{\lambda q_{0}}{4\pi \epsilon_{o} r}$$

It is not as simple you think .. If so then I'am sure Kushal don't post it .. Since that was very easy and standard problem .. :D

Total tension will be developed due to electrostatic force by $$q_0$$ and the ring.

If the question was to find the increase in tension when $$q_o$$ was placed then your answer is correct.
