Question

The angular amplitude of a simple pendulum is `theta_(0)`. The maximum tension in its string will be
A. `mg (1-theta_(0))`
B. `mg(1+theta_(0))`
C. `mg(1-theta_(0)^(2))`
D. `mg(1+theta_(0)^(2))`

Answer 1

Correct Answer - D
`T_(max) = mg+(mv_(max^(2)))/(l) = mg +(2mgl)/(l) (1-cos theta_(0))`
