As we know that electrostatic force is a conservative force
so we can say by the condition of conservative force
here we can rearrange the above equation as
now integrate both sides
Now we know by the definition of work done by a force is given by
now work done by conservative force is given as
Now from above work done by electric field to move charge from one point to other is given as
so here work done is given as
so change in potential energy is given by work done
Answer:
Explanation:
potential energy of water is converted into heat energy
P E = mgh = m x 9.8 x 111
= 1087.8 m .
Let rise in temperature θ
m x s x θ = heat absorbed
m x s x θ = 1087.8 m
m x 4182 x θ = 1087.8 m
θ = 0.26 degree celsius .
which law of energy has never been broken?
Conservation.

Answer:
For an object resting upon a non-accelerating surface, the normal force is equal to the ... Suppose that a person weighs 800 N and sits at rest upon a table. ... applying a downward force of 200 N. With the additional downward force of 200 N acting upon the person, the total upward force must be 1000 N.
