A proton goes undeflected in a crossed electric and magnetic field (the fields are perpendicular to each other) at a speed of `10^(5)m//s`.The velocity is perpendicular to both the fields.When the electric field is swithed off.the proton moves along a circle of radius `2 cm`.Find the magnitudes of electric and the magnitic fields.Take the mass of the proton`=1.6xx10^(-27) kg`.

A proton goes undeflected in a crossed electric and magnetic field (the fields are perpendicular to each other) at a speed of 2.0X10^5 ms^(-1). The velocity is perpendicular to both the fields. When the electric field is switched off, the proton moves along a circle of radius 4.0 cm. Find the magnitudes of the electric and the magnetic fields. take the mass of the proton =1.6 X10^(-27) kg.
