Answer:
Workdone = 1250Nm
Explanation:
<u>Given the following data;</u>
Force, F = 500N
Distance, d = 2.5m
Workdone is given by the formula;
Substituting into the equation, we have
Workdone = 1250Nm
Therefore, the actual work done by the worker is 1250 Newton-meter.
If a car is moving with uniform velocity, then there is
no net force acting on it.
The force of the engine is exactly enough to balance
the forces of friction and air resistance against the car.
Also notice that there can't be any centripetal force, and the
car can't be on a curve. If it's moving with "uniform velocity",
that means steady speed in a straight line.
Answer:
The magnitude of charge on each sphere is
.
Explanation:
Given that,
Force of repulsion between the charges, F = 22 mN
The distance between spheres, r = 16 mm = 0.016 m
It is mentioned that both the spheres carry equal charges. The force between charges is given by :




So, the magnitude of charge on each sphere is
. Hence, this is the required solution.
