mass of Bob of a simple pendulum is ten gram it makes 10 oscillation in 15 second passes the mean position with a speed 4 cm per second work done by tension in the suspension thread in oscillation is:

Dear Student,
Please find below the solution to the asked query:

The work done by the tension in a simple pendulum is zero. Because for work to be done the force acting and the displacement should be in the same direction but in case of simple pendulum the displacement is in a direction perpendicular to the tension in the string and hence the work done by the tension is zero.
