The apparent weight of a body,when it is travelling upwards with an acceleration of $2 \ m/s^2$ and its mass is $10 \ kg$,will be ......... $N$.

$A$ mass is hanging on a spring balance which is kept in a lift. The lift ascends with an acceleration. The spring balance will show in its readings:

$A$ man of mass $75\, kg$ is standing in an elevator which is moving with an acceleration of $5\, m/s^2$ in the upward direction. The apparent weight of the man will be ........... $N$ $(g = 10\, m/s^2)$.

In the figure,the reading of the spring balance will be $......\,N$ $\left[ g = 10\,m/s^2 \right]$.

The mass of a person sitting in a lift is $50 \, kg$. If the lift is coming down with a constant acceleration of $10 \, m/s^2$,then the reading of the spring balance will be ......... $N$ $(g = 10 \, m/s^2)$.

$A$ block is lying at rest inside a bus. What is the maximum acceleration of the bus such that the block remains stationary? (The static friction coefficient $\mu = 0.2$,acceleration due to gravity $g = 10 \ m/s^2$)
