Two small balls, each having charge q, are suspended by two insulating threads of equal length L fron a hook in an elevator. The elevator is freely falling. Calculate the angle etween the two threads and tension in each thread.

A

`180^(@),(1)/(4piepsilon_(0))(Q^(2))/((2L)^(2))`

B

`90^(@),(1)/(4piepsilon_(0))(Q^(2))/(L^(2))`

C

`180^(@),(1)/(4piepsilon_(0))(Q^(2))/(2L^(2))`
