A simple pendulum is released from rest at the horizontally stretched position. When the string makes an angle with the vertical, the angle which the acceleration vector of the bob makes with the string is given by-

Options

  1. A=0
  2. B= ⁻¹ ( 2 )
  3. C= ⁻¹(2 )
  4. D= / 2

Correct answer

B. = ⁻¹ ( 2 )

Step-by-step solution

By energy conservation = a _ t / a _ c
