Answer:
C) 1200 rpm
Explanation:
= Diameter of bigger pulley = 24 inch
= Diameter of smaller pulley = 8 inch
= Speed of bigger pulley = 400 rpm
= Speed of smaller pulley
The relation between revolutions per minute and diameter is that they are inversely proportional.
The number of revolutions per minute of the smaller pulley is 1200 rpm
The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.
<h3>What is a magnetic field?</h3>It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.
The given data in the problem is;
I is the current = 6.50 A
B is the magnetic field=f 2.71 X 10⁻⁵ T
The force on the wire is;
Hence, the force on one of the wires will be 0.000264 N.
