A potential difference of 35 mV is developed across the ends of a 12.0-cm-long wire as it moves through a 0.27 T uniform magnetic field at a speed of 6.0 m/s. The magnetic field is perpendicular to the axis of the wire. What is the angle between the magnetic field and the wire's velocity?

Angle between magnetic field and wire velocity is

Explanation:

We have given potential difference e = 35 mV = 0.035 volt

Length of the wire l = 12 cm = 0.12 m

Velocity v = 6 m/sec

Magnetic field B = 0.27 T

It is known that potential difference developed

So angle between magnetic field and wire velocity is

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
