NEET 2026 Physics question
The sum of kinetic energy and potential energy of a simple pendulum bob is 0.02 joule. The speed of the simple pendulum bob at equilibrium position is approximately: (Consider mass of the bob = 20 g)
Answer: (2)
Solution
Total mechanical energy is conserved. At the equilibrium (mean) position the potential energy (measured from that position) is zero, so all of the energy is kinetic: .
