zero
mg sino
mg coso
1​

Answer 1

Answer:

zero

Explanation:

Answer 2

The correct answer is Zero.

• A simple pendulum is defined to have a point mass.
• The work done by the tension in the string of a simple pendulum in one complete oscillation is zero.
• The work done by the tension in the string of a simple pendulum in one complete oscillation is zero.
• As the net displacement in one complete oscillation is Zero work done is Zero.
• Also force is perpendicular to displacement thus work done is Zero.
• So, the force is also zero in a simple pendulum.
