JEE Main 2024 — Work Power Energy Question with Solution

JEE Main 2024 (31 Jan Shift 1)

Question

An artillery piece of mass M1 fires a shell of mass M2 horizontally. Instantaneously after the firing, the ratio of kinetic energy of the artillery and that of the shell is :

Choose an option

Show full solutionCorrect option: B
Correct answer
BM2M1

Step-by-step explanation

As linear momentum will be conserved, p⇀1=p⇀2

Now, kinetic energy can be written as KE=p22M.

Also p is the same for both masses. We can write,

KE∝1m

⇒KE1KE2=p22M1p22M2=M2M1
