If a body of mass $m$ is carried by a lift moving with an upward acceleration $a$, then the forces acting on the body are
(i) the reaction $R$ on the floor of the lift upwards
(ii) the weight $mg$ of the body acting vertically downwards.
The equation of motion will be given by
If a body of mass $m$ is carried by a lift moving with an upward acceleration $a$, then the forces acting on the body are
(i) the reaction $R$ on the floor of the lift upwards
(ii) the weight $mg$ of the body acting vertically downwards.
The equation of motion will be given by
$R = mg - ma$
$R = mg + ma$
$R = ma - mg$
$R = mg \times ma$
If a body of mass $m$ is carried by a lift moving with an upward acceleration $a$, then the forces acting on the body are
(i) the reaction $R$ on the floor of the lift upwards
(ii) the weight $mg$ of the body acting vertically downwards.
The equation of motion will be given by
$N-m g=m a$
$R-m g=m a$
$R=m a+m g$
