Statement -1 : When momentum `(p)` of a body is increased by `50%`, its KE `(E)` increases by `125%`.
Statement-2 : This is because `p prop upsilon` and `E prop upsilon^(2)`

Options

A. Statement - 1 is ture , statement -2 is true, and statement-2 is correct explanation of statement -1.
B. Statement-1 if ture, statement-2 is true, but statement -2 is not a correct explanation of statement-1.
C. Statement-1 is true, but statement -2 is false.
D. Statement-1 is false, but statement-2 is true.

Answer

A

Explanation

As `p` is increased by `50%`, velocity `upsilon` increases by `50%` becoming `3//2` times. ltbr. Therefore, `K.E.(E)` becomes `(9//4)` times. Increase in `K..E.=(((9)/(4)E-E))/(E)xx100=125%`
Both the statements are true, and latter is correct explanation of the former.
