JEE Main Physics question

Physics Laws of Motion JEE Main

**Statement I:** The slope of a momentum versus time curve gives us the acceleration. **Statement II:** Acceleration is given by the rate of change of momentum.

(A)Statement I is true, Statement II is true; Statement II is a correct explanation for Statement I
(B)Statement I is true, Statement II is true; Statement II is not a correct explanation for Statement I
(C)Statement I is true, Statement II is false
(D)Statement I is false, Statement II is trueCorrect

Answer: (D)

Solution

The slope of a momentum–time curve (dp/dt) equals the net force, not the acceleration (these are equal only if mass is taken as unity), so Statement I is false as a general claim. Statement II, read as the
