# Let θ Denote the Angular Displacement of a Simple Pendulum Oscillating in a Vertical Plane. If the Mass of the Bob Is M, the Tension is the String Is Mg Cos θ - Physics

MCQ

Let θ denote the angular displacement of a simple pendulum oscillating in a vertical plane. If the mass of the bob is m, the tension is the string is mg cos θ

#### Options

• always

• never

• at the extreme positions

• at the mean position.

#### Solution

at the extreme positions

Tension is the string , $\text{T} = \frac{\text{mv}^2}{\text{r}} - \text{mg}\cos\theta$

When v = 0,

$\left| \text{T} \right| = \text{mg}\cos\theta$

That is, at the extreme positions, the tension is the string is mgcosθ.

Is there an error in this question or solution?
