JEE Main 2024 Physics question
A particle of mass m moves on a straight line with its velocity increasing with distance according to the equation , where α is a constant. The total work done by all the forces applied on the particle during its displacement from x = 0 to x = d, will be:
Answer: (C)
Solution
By the work–energy theorem, W = ½m(α√d)² − 0 = mα²d/2.
