MHT CET 2023 Physics question
A simple pendulum of length 2 m is given a horizontal push through angular displacement of 60⁰. If the mass of bob is 200 gram, the angular velocity of the bob will be (Take Acceleration due to gravity = 10 m/s²) (, )
Answer: (C)
Solution
Energy conservation between the mean position and the extreme position gives with , so and rad/s (the mass of the bob, 200 g, cancels out and
