A car is moving on a plane inclined at $\displaystyle 30$° to the horizontal with an acceleration of $\displaystyle 10 \mathrm{~ms}^{-2}$ 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 $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ )
