Answer:
t = 0.97 s
Explanation:
Given that,
height, h = 4.7 m
We need to find the time taken by the object to fall 4.7 m.
Let it is t. Using second equation of kinematics to solve it such that,
u is initial velocity, u = 0
So,
So, the required time is equal to 0.97 seconds.
The proton's electrostatic force exerted on the electron will be 3.5×10¹² N.
<h3>What is the electrostatic force?</h3>It is a force imposed by one charge on another as a result of the field.
The electrostatic force produced by one line charge on another line charge separated by r is determined by the charge potency of each charge as well as the separation distance between them.
The electrostatic force is found as:
Hence, the proton's electrostatic force exerted on the electron will be 3.5×10¹² N.
