    A car is moving on a plane inclined at 30∘30^{\circ} to the horizontal with an acceleration of 10 ms−210{\text{ }ms}^{- 2} parallel to the plane upward. A bob is suspended by a string from the roof of the car. The angle in degrees which the string makes with the vertical is (Take g=10 ms−2g = 10{\text{ }ms}^{- 2} )
