A particle of mass M = 0.2 kg is initially at rest in xy plane at a point (x = -l, y = -h) where l = 10m and h = 1m. The particle is accelerated at time t = 0 with a constant acceleration `a = 10 m/s^2` along the positive x-direction. Its angular momentum and torque w.r.t origin in SI units are represented by `vec(L)` and `vec(tau)` resp. If ` hat(k) = hat(i) x hat(j)` then which of the following statements is/are correct?

Options

A. The particle arrives at point (x = l, y = -h) at time t = 2s
B. `vec(tau) = 2 hat(k)` when the particle passes through the point (x = l, y = -h)
C. `vec(L) = 4 hat (k)` when the particle passes through the point (x = l, y = -h)
D. `vec(tau) = hat(k)` when the particle passes through the point (x = 0, y = -h)
