What will be the ratio of kinetic energies of alpha particle and proton if their linear momentum will be same?
Correct answer: B. 1: 4
- A. 18 : 1
- B. 1: 4
- C. 4 : 1
- D. 104 : 1
Explanation
Mass of α-particle=6.644x 10-27kgmass of proton = 1.672 x 10-27 kgPα =Pp

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
