Question

A bob of mass 0.2 kg is

suspended from the roof of a car with a massless string. The car is accelerating horizontally ala constant acceleration of 5/5 m/s2. Find the tension in the string​

Answer 1

Explanation:

First, we will derive a result for conical pendulum in stationary.

From the above two equations we get

Now in accelerating the car , with respect to an inside observer, there will be a 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 45

From these two conditions H =2π

Answer 2

Explanation:

The above answer is correct Ok!
