What is the difference between Electromagnetic Force and Electromagnetic Field?​

Physics
1 answer:
sladkih [1.3K]3 years ago
4 0

Answer:

Electromagnetic force creates electromagnetic field.

Explanation:

Electromagnetic force acts between charged particles and this force is the combination of all electrical and magnetic forces. On the other hand, the electromagnetic field is detected by the force it exerts on other magnetic particles and moving electric charges. So, electromagnetic field is created by electromagnetic force. Without this force there cannot be any electromagnetic field.

What is the Gravitational Potential Energy of a 30 kg box lifted 1.5 meters off the ground?
juin [17]

Answer:

<h2>441 J</h2>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

PE = 30 × 9.8 × 1.5

We have the final answer as

<h3>441 J</h3>

Hope this helps you
