point B.

Expert Solution

Step 1

There are two force acting on the bob of the pendulum one is due to the force of the gravity that acts downward and tension on the string directed towards the point of suspension.

When the bob is the lowest point at C. The force due to gravity and the tension are acting in opposite direction.

When the bob is at point B. String makes an angle of $θ$ of with the vertical direction. By resolving the forces acting on the bob. One component is perpendicular component and the other is towards the direction of acceleration.

Where we resolve the force acting due to gravity, the perpendicular component directed opposite to the tension force acting on the bob.
