The correct answer is the last option. The force that moving, charged particles exert on one another is called electromagnetic force. This force involves physical interaction between two electrically charged particles. It is seen as electromagnetic fields such as electric fields, magnetic fields and light.
I believe the answer is A) Less work in less time.
Answer:
Explanation:
Let force acting on the card = F . let its x component be F_x
F_x . 3 = 300
F_x = 100
similarly ,
F_y . 4 = 400
F_y = 100
Total F = √ 3² + 4²
= 5 N
2 ) Force of the cart on the student = 5 N ( Reaction force)
3) Distance moved by the cart = 3 + 4 = 7m
4) magnitude of displacement = 5 m
