Explain Centripetal force??
Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pulling the body absent of line. When the force acts on the body from a fixed point, like a body moves in a circle, and the force towards the centre is known as a centripetal force.
Self inductance: When current through a coil changes, the changing flux induces an emf that opposes the current flow. This emf is the result of self inductance and is called '
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
