When a charged particle enters perpendicular to uniform magnetic field, path followed by it is ______

When a charged particle moves in a magnetic field its kinetic energy _______ .

Two particles A and B having equal charges are placed at distance d apart. A third charged particle placed on the perpendicular bisector at a distance x will experience the maximum Coulomb’s force when :

If the size of the particle scattering the light is smaller than the wavelength of incident light then the scattering is called ...... scattering.

Track of three charged particles in a uniform electroastatic field give the sign of the three charges which particle has the highest charge to mass ratio

Figure shows tracks of three charged particles in a uniform electrostatic field. Give the signs of the three charges. Which particle has the highest charge to mass ratio ?

A charges particles particle is kept in equilibrium in the electric field between the plates of millikan oil drop experiment. If the direction of the electric field between the plates is reversed, then calculate acceleration of the charged particle.
