Answer:
2.09 rad/s
Explanation:
Given that,
A toy car makes 4 laps in 12 s.
We need to find the angular velocity of the toy car. We need to find the angular velocity of the toy car.
4 laps = 25.13 rad
So,
So, the angular velocity of the toy car is 2.09 rad/s.
The electrostatic force between two charges is given by
where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the charges
In our problem,
Therefore the electrostatic force is
Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities.
