A car is acclerating down on an inclined plane as shown in the figure with acceleration a=g. Now find time period of SHM of the pendulum present inside the car.

Options

A. `T=2pisqrt((l)/(g))`
B. `T=2pisqrt((l)/(g cos 30^(@)))`
C. `T=2pisqrt((l)/(gsqrt(2)))`
D. `T=2pisqrt((l cos 60^(@)))/(g)`

Explanation

`g_(l)=("Tension")/(m)`
`=sqrt(((mg)^(2)+(mg)^(2)+2(mg)(mg)sin20^(@))/(m))`
`g_(l)=g`
`T=2pisqrt((l)/(g))`
