If a charged particle kept at rest experiences an electromagnetic force,

If a charged particle at rest experiences no electromagnetic force, then electric field in that region

Two particles A and B having charges 8.0 xx 10 ^(-6) C and -2.0 xx 10(-6) C respectively are held fixed with a. separtion of 20cm. Where should a thired charged. particle be placed so that it dose not experience a net electric force?.

The force on a charged particle due to electric and magnetic fields is given by vecF=qvecE+qvecvXvecB . Suppose vecE is along the X-axis and vecB along the Y-axis. In what direction and with what minimum speed v should a positively charged particle be sent so that the net force on it is zero?

A charged particle is moved along a magnetic field line. The magnetic force on the particle is

Two chargea 2.0xx10^(-6) C and 1.0xx10^(-6) C are placed at a separation of 10 cm. where should a third charge be placed such that it experiences no net force due to these charges.

Suppose a charged particle moves with a velocity v near a wire carrying an electric current. A magnetic force, therefore, acts on it. If the same particle is seen form a frame moving with velocity v in the same direction the charge will be found at rest. Will the magnetic force become zero in this frame?

If a charge is placed at rest in an electric field, will its . path be along a line of force ? Discuss the situation when . the lines of force are straight and when they are curved.

The magnetic force acting on a charged particle of charge - 2muC in a magnetic field of 2T acting in y direction, when the particle velocity is (2hati + 3 hatj) xx 10^6 ms^-1 , is:
