A uniform magnetic field exists perpendicular to the plane of the figure and a uniform electric field exists in the plane of the figure in positive y direction. A charged particle, when projected along xy plane moves along the path shown in the figure. Is the particle positively charged or negatively charged?

A charged particle is projected perpendicular to the direction of uniform electric field. It's path in the region of the field will be

In a region of space a uniform magnetic field perpendicular to the plane of the page and directed towards reader exists. A particle has a trajectory as shown in fig. The particle is-

In the fig shown XX represents a vertical plane perpendicular to the plane of the fig. To the right of this plane there is a uniform horizontal magnetic field B directed into the plane of the fig. A uniform electric field E exists horizontally perpendicular to the magnetic field in entire space. A charge particle having charge q and mass m is projected vertically upward from point O. It crosses the plane XX after time T. Find the speed of projection of the particle if it was observed to move uniformly after time T. It is given that qE = mg.

There exists a uniform magnetic field perpendicular to the plane of the figure in a cylindrical region of radius a. The magnetic field is increasing at a constant rate of alpha Ts^(-1) . A particle having charge q is at a point P outside the field region. The particle is slowly moved to infinity. Calculate work done by the external agent on the particle if- (a) the particle is moved in radial direction OP. (b) the particle is moved in a direction perpendicular to OP along PQ.

A uniform electric field E exists in a region of space. A charged particle is projected in the plane of electric field making an angle 0 with the direction of field. Is it possible to make the particle move in a straight line by applying a uniform magnetic field?

the figure shows the path of A positively charged particle through a rectangular region of uniform electric field as shown in the figure. the direction of deflection of particle 2, 3 and 4 is

A uniform magnetic field exists in the plane of paper pointing from left to right as shown in figure. In the field, an electron and a proton move as shown. The electron and the proton experience:
