A cork suspended from the bottom of a container filled with water with a string as shown in figure. If the container accelerate in a horizontal direction towards right. Which one is correct ?

Options

A. Inclination of string with vertical is `tan^(-1)(a//g)` towards left
B. Inclination of string with vertical is `tan^(-1)(a//g)` towards right
C. Inclination of string with vertical is `pi//2-tan^(-1)(a//g)` towards left.
D. Inclination of string with vertical is `pi//2-tan^(-1)(a//g)` towards right.

Explanation

`mgL sin theta=ma L cos theta`
`rArr tantheta=(a)/(g)`
`theta=tan^(-1)((a)/(g))`
