Question

Two particles A and B are identical except that in passing through matter A interacts with a force that is stronger than the one with which B interacts.

Which of the following is true when comparing what happens when these particles pass through some material?

A. On average, A will penetrate through more material before interacting than B.

B. On average, A will penetrate through less material before interacting than B.

C. On average, A and B will penetrate through the same amount of material before interacting.

Answer 1

For the given question, Particle A interacts with matter with a force greater than the one with which Particle B interacts.

Now, lets see the situation where particle A is passed through a matter then, particle will experience more force with the matter. Therefore, matter will provide more hinderence for the particle A, than particle B. So the particle A will not be able to move more fastly than B and the energy of particle A will be more utilized by the matter compare to particle B.

Hence, when we pass both the particles A and B through the matter, the particle A will rest behind the particle B.

Therefore, the option (B) is correct.
