372208 A satellite in a force free space sweeps stationary interplanetary dust at a rate. \(\left(\frac{\mathbf{d M}}{\mathbf{d t}}\right)=\alpha \mathrm{v}\). The acceleration of satellite is

1 \(-\frac{2 \alpha v^{2}}{M}\)
2 \(-\frac{\alpha v^{2}}{M}\)
3 \(-\frac{\alpha v^{2}}{2 M}\)
4 \(-\alpha v^{2}\)
LAWS OF MOTION (ADDITIONAL)

372209 Physical independence of force is a consequence of

1 Third law of motion
2 Second law of motion
3 First law of motion
4 All of these
