Question

When the bob is in the central position, the forces are

• A. balanced
• B. unbalanced
• C. sometimes balanced and sometimes unbalanced
• D. none of these

Answer 1

The correct option is A balanced

When the bob is in central position only two forces are acting on the bob

1. Gravitational force
2. tension force

Both the forced act in vertical directions and the displacement in vertical direction is zero

Hence gravitational and tension force balance each other

So the forces are balanced
