A car is accelerating horizontally with constant acceleration a=10m/s2. One end of a light string is attached to the roof of the ceiling and there is a small bob at other end of string. The bob is given an initial velocity such that it continues to move in uniform circular motion with respect to an observer inside the car. The bob moves such the maximum vertical separation between two points of its path is h=1m. The length of the string is  and acceleration due to gravity g=10m/s2. If the angular speed of the bob in rad/s is √x .find the value of x.

Verified Answer
A car is accelerating horizontally with constant accelerationa=10m/s2....
First we will drive a result for conical pendulum in stationary car. see figure
Now in acceleration car, with respect to an inside observer, there will be pseudo force acting on the particle opposite
to the acceleration of the car, and hence perpendicular to the weight. since a=g, the effective gravity will be
  inclined at an angle of 450 with the verticle axis.
