Two bodies of unequal masses are dropped from a tower. At any instant, they have equal
Options
- AMomentum
- BAcceleration
- CPotential energy
- DKinetic energy
Correct answer
B. Acceleration
Step-by-step solution
When two bodies are dropped from a height, they fall freely under gravity. The acceleration of a freely falling body is the acceleration due to gravity g , which is independent of the mass of the body. Therefore, both bodies will have the same acceleration at any instant. Momentum p = mv , kinetic energy K = 1 2 mv^2 , and potential energy U = mgh all depend on the mass m of the body. Since the masses are unequal, their momentum, kinetic energy, and potential energy will be different. Answer : Acceleration
