Answer:
750W
Explanation:
Given parameters:
Weight = 1 x 10³N = 1000N
Distance = 1.5m
Time = 2s
Unknown:
Power = ?
Solution:
Power is the rate at which work is done
Work is the force applied on a body to move it through a particular distance
Work = force x distance
Power =
Now, work = 1000 x 1.5 = 1500J
So;
Power = = 750W
The potential energy will be 1.46*10^-4J.
To find the answer, we have to know about the torque acting on a current loop in a uniform magnetic field.
<h3>How to find the potential energy of the loop?</h3>- We have the expression for torque acting on a current loop in a uniform magnetic field as,
where; M is the magnetic dipole moment, B is the magnetic field , and theta is the angle between M and B.
- As we know that, the torque is equal to force times the perpendicular distance. Thus, it is equivalent to the work done. This work is stored as the potential energy in the loop.
- Thus, the potential energy will be,
Thus, we can conclude that, the potential energy will be 1.46*10^-4J.
