Column 1 gives situations involving a charged particle which may be realized 
under the condition given in column-II. Match the situations in column in
column I with the conditions in Column-II.

	Column–I		Column–II
A	Increase in speed of a charged particle.	P	Electric field uniform in space and constant in time.
B	Exert a force on an electron initially at rest.	Q	Magnetic field uniform in space and constant in time.
C	Move a charged particle in a circle with uniform speed.	R	Magnetic field uniform in space but varying with time.
D	Accelerate a moving charged particle.	S	Magnetic field non-uniform in space but constant with time.
		T	None of these
