Let theta denote the angular displacement of a simple pendulum oscillating in a vertical plane. if the mass of the bob is m, then the tension in string is

So the tension  in the string T =mg cosθ

Explanation:

Now given that

mass of bob = m

Angle from vertical plane =θ

Lets T is the tension in the string

From the diagram

Weight of bob have two component ,first one(mg cosθ) balance the tension in the string and other one(mg sinθ)  make the bob to move in the plane.

So the tension  in the string T =mg cosθ

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
