270098 A ball is dropped from a spacecraft revolving around the earth at a height of \(1200 \mathrm{~km}\). What will happen to the ball?

1 It will continue to move with velocity \(\mathrm{V}\) along the original orbit of spacecraft
2 It will move with the same speed tangential to the space craft
3 It will fall down to the earth gradually
4 It will go far in space

270099 A body is under the action of three forces \(\vec{F}_{1}, \vec{F}_{2}\) and \(\overrightarrow{F_{3}}\). In which case the body cannot undergo angular acceleration?

1 \(\vec{F}_{1}, \vec{F}_{2}\) and \(\overrightarrow{F_{3}}\) are concurrent
2 \(\vec{F}_{1}+\overrightarrow{F_{2}}+\overrightarrow{F_{3}}=0\)
3 \(\vec{F}_{1}, \vec{F}_{2}\) is parallel to \(\vec{F}_{3}\) but the three forces are not concurrent
4 \(\vec{F}_{1}\) and \(\overrightarrow{F_{2}}\) act at the same point but \(\overrightarrow{F_{3}}\) acts at different point.

270094 A man drops an apple in the lift. He finds that the apple remains stationary and does not fall. The lift is

1 going down with constant speed
2 going up with constant speed
3 going down with constant acceleration
4 going up with constant acceleration
Laws of Motion

270095 Internal force can change

1 linear momentum as well as kinetic energy
2 linear momentum but not the Kinetic energy
3 the kinetic energy but not linear momentum
4 Neither the linear momentum nor the kinetic energy
