Problem

A particle of mass mm moves on a straight line with its velocity increasing with distance according to the equation v=αxv = \alpha\sqrt{x}, where α\alpha is a constant. The total work done by all the forces applied on the particle during its displacement from x=0x = 0 to x=dx = d, will be: [April 9, 2024 (I)] (a) m2α2d\frac{m}{2\alpha^2 d} (b) md2α2\frac{md}{2\alpha^2} (c) mα2d2\frac{m\alpha^2 d}{2} (d) 2mα2d2m\alpha^2 d
