Assertion : Two identical balls are charged by q. They are suspended from a common point by two insulating threads l each. In equilibrium, the angle between the tension in the threads is `180^(@)`. (Ignore gravity).
Reason : In equilibrium tension in the spring is
`T=1/(4pi epsi_(0)) (q.q)/l^(2)`
A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion
B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
C. If Assertion is true but Reason is false
D. If Assertion is false but Reason is true
