A plumb bob is hanging from the ceiling of car. If the car move with acceleration a , the angle made by the string with the vertical is

Options

  1. A⁻¹ ( a g )
  2. B⁻¹ ( g a )
  3. C⁻¹ ( g a )
  4. D⁻¹ ( a g )

Correct answer

A. ⁻¹ ( a g )

Step-by-step solution

When car moves towards right with acceleration a then due to Pseudo force the bob will tilt in backward direction making an angle with vertical. = ⁻¹ ( a g )
