|A power line carrying a current of 200 A runs from south to north. At a certain time, an electron in the air moves parallel to the power line along the same direction. The speed of the electron is 25000 m/s and the distance between the electron and power line is 0.05 m. What are the direction and magnitude of the magnetic force on the electron? I = 200 A South North U = 25000 m/s 0.05 m

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
