List of top Physics Questions on laws of motion asked in WBJEE

The minimum force required to start pushing a body up a rough plane is \( F_1 \) while the minimum force needed to prevent it from sliding down is \( F_2 \). The plane makes an angle \( \theta \) with horizontal such that \( \tan\theta = 2\mu \). The ratio \( F_1/F_2 \) is
A force \( \vec{F}=ai+bj+ck \) is acting on a body of mass \( m \). The body was initially at rest at the origin. The coordinates of the body after time \( t \) will be
What force \(F\) is required to start moving this 10 kg block shown in the figure if it acts at an angle of \(60^\circ\) as shown? (\(\mu_s = 0.6\)).
