Question

A simple pendulum of length 1 m has a bob of mass 100 gm at its free end, is swinging with an angular amplitude of π/3 radian. What is the tension in the thread when the bob passes through the equilibrium position ?​

Answer 1

Answer:

$\sqrt{10 \times 3}$

Explanation:

just use simple law of conservation of energy and laws of motion. At extreme position speed will be zero and hence the kinetic energy at the lowest point will be converted to the potential energy at the highest point and by finding his energy in liquid in them the question is solved
