Question

The direction of motion of the corpuscles is unaffected by the force of gravity due to

1) high speeds of corpuscles

2) negligible mass of corpuscles

3) both 1 and 2           

4) neigther 1 nor 2


​

Answer 1

The direction of motion of the corpuscles is unaffected by the force of gravity due to

1. high speeds of corpuscles
2. negligible mass of corpuscles
3. both 1 and 2
4. neither 1 nor 2.

solution : in free space, corpuscles travel with a velocity 3 × 10^8 m/s. as it is clear that it is very high value of speed.

mass of each corpuscles is very very low. even mass of corpuscles is negligible.

but we know, force of gravity is experienced by any particles only when these have mass.

for corpuscles,force of gravity acted on corpuscles is negligible and it can't defect their path because of their very high velocity.

Therefore, the direction of motion of corpuscles is unaffected by the force of gravity because of their very high velocity and practically zero mass.

hence option (3) both 1 and 2.
