<u>Answer:</u>
3.5 x 10^-8 J
<u>Explanation:</u>
We are given,
force experienced by a charge = 3.6 x 10^-4 N; and
distance of charge from the source of electric field = 9.8 x 10^-5 m
We know that, <em>Energy = force x distance</em>
therefore, to find the potential energy of the charge, we need to multiply its applied force with the given distance to get:
Electric potential energy of a charge = (3.6 x 10^-4) × (9.8 x 10^-5) = 3.5 x 10^-8 J
Therefore, the potential energy of a charge is 3.5 x 10^-8 J.
Answer:
According to your question although I think an object undergoing uniform circular motion is moving with a constant speed. Nevertheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards,therefore a force perpendicular to an objects velocity change the direction of the velocity but not its magnitude.
The ball has the greatest potential energy when it reaches the top of its flight. Option C is correct.
<h3>What is
potential energy?</h3>
The potential energy of a body or object is due to its position. The ball has the greatest potential energy when it reaches the highest point.
Where,
- potential energy
- mass
- gravitation acceleration
- height
Since the mass and gravitation acceleration is constant hence potential energy will be directly proportional to the height of the ball.
Therefore, the ball has the greatest potential energy when it reaches the top of its flight.

IB QuestionbankExplanation:
The approximate acceleration of the car would be <span>3.00
</span>How? We have to use the formula to find the velocity.
v = d/t = 120/6.32
v = 19
Then plug the factor into the acceleration formula to find the acceleration:
a = v/t = 19/6.32
a = 3.00
So, the approximate acceleration of the car would be 3.00
