QAIPM-2000-Ph-3032: NEET 2000 Physics - Class 11 AIPM-2000-Ph-3032 Solution: The bob of simple pendulum having length l, is displaced from…

The bob of simple pendulum having length l, is displaced from mean position to an angular position θ\theta with respect to vertical. If it is released, then velocity of bob at equilibrium position

Multiple Choice Options

  • A 2gl(1−cos⁡θ)\sqrt{2gl(1-\cos\theta)}
  • B 2gl(1+cos⁡θ)\sqrt{2gl(1+\cos\theta)}
  • C 2glcos⁡θ\sqrt{2gl\cos\theta}
  • D 2gl\sqrt{2gl}

Step-by-Step Verified Solution

In _ O A C , cos _ _ = A / l _ O A = l c o s _ _ A B = l ( 1 _ cos _ _ ) = h At point, C the velocity of bob = 0. The vertical acceleration = g _ v 2 = 2 g h _ v = 2 g l ( 1 _ cos _ _ )
