Answer:
It is always said that mass is same everywhere.
Not necessarily, object A could also be neutral, and becoming a dipole due to object B's charge. A charged object can induce a dipole in a neutral object, and that object would then become attracted without being charged.
Answer:
Kinetic energy is energy an object has because of its motion. A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
Explanation:
there hope this helps
We know, Potential Energy = Force * Height
Here, F = 40 N
h = 5 m
Substitute their values,
U = 40 * 5
U = 200 J
In short, Your Answer would be Option A
Hope this helps!
Answer:
the box has vertical force on the table
Explanation:
There can be no single isolated force, for every action there must be a force of reaction of ingual magnitude and direction, but in the opposite direction
