A positive charge enters in the region of transverse magnetic field as shown in figure. Velocity of charge is in such a way that charge passes through both inward and outward magnetic field regions, then possibly correct path of the charge is

A particle enters the region of a uniform magnetic field as shown in figure. The path of the particle inside the field is shown by dark line. The particle is :

Four particles enter a region of uniform magnetic field. Their trajectories are shown in figure. What are the signs of the charge of all four particles ?

A charge q moves region in a electric field E and the magnetic field B both exist, then the force on its is

The figure shows two regions of uniform magnetic field of strengths 2B and 2B. A charged particle of mass m and charge q enters the region of the magnetic field with a velocity upsilon = (q B w)/(m) , where w is the width of each region of the magnetic field. The time taken by the particle to come out of the region of the magnetic field is

Assertion : Magnetic field interacts with a moving charge and not with a stationary charge. Reason : A moving charge produces a magnetic field.

In a region where both non-zero uniform electric field and magnetic field coexist, the path of a charged particle

A charge is moving through a magnetic field. The force acting on the charge is maximum when the angle between the velocity of charge and the magnetic field is _______
