Answer:
c. V = k Q1 * Q2 / R1 potential energy of Q1 and Q2 separated by R
V2 / V1 = (R1 / R2) = 1/4
V2 = V1 / 4
Answer:
A. The bus has more kinetic energy than the car.
Explanation:
We know that
Kinetic energy is the energy amount possessed from the body as in the motion
Also, the following formula should be used to determine the kinetic energy
Kinetic energy = 1 ÷ 2mv²
Here m represents the mass of the body
and v represents the velocity of the body.
Therefore it should be based on the mass & velocity of the body
In the case when the passenger bus have more kinetic energy as compared to the car so this is because of the the big mass
Therefore, the first option is correct
