उत्तर

Clearly, from the diagram (a), the variation can be related as x = t

⇒ `(dx)/(dt)` = 1 m/s

ax = 0

From diagram (b) y = t2

⇒ `(dy)/(dt)` = 2t or ay = `(d^2y)/(dt^2)` = 2 m/s2

Hence, Iy = may = 500 × 10–3 × 2 = 1 N  .....(∵ m = 500 g)

Fx = max = 0

Hence, net force, F = `sqrt(F_x^2 + F_y^2)` = Fy = 1 N  .....(along y-axis)
