Explanation:
- The impulse exerted on Katelyn when she was on the force plate, is equal to the change in her momentum, according to Newton's 2nd Law.
- Assuming as the positive direction the upward direction (coincident with the positive y-axis) we can express the initial momentum as follows:
- By the same token, the final momentum is as follows:
- As we have already said, the impulse J is just equal to the change in momentum, i.e., the difference between (2) and (1):
Answer:
Explanation:
Given
Force of repulsion between two charge particle is given by force F
Electrostatic force is given by
where and
is the charges of particle
r=distance between charge particle
when charges are doubled and distance is reduced to half
i.e. q become 2 q and r becomes 0.5 r
