Makovka662 [10]3 years ago
4 0

Answer:

\theta=\tan^{-1}\dfrac{a}{g}

Explanation:

Here we are assuming that the car is moving in a straight line and is traveling on a smooth surface. When the car is moving with acceleration a the bob moves in the opposite direction with the same acceleration. Gravity is acting on the bob so it is experiencing an acceleration of g downwards.

The angle between the acceleration a and the acceleration due to gravity g is

\theta=\tan^{-1}\dfrac{a}{g}.
