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:

A uniform magnetic field vecB of magnitude 0.2 T exists in the plane of paper from left to right. A conducting wire, bent in an irregular manner, and carrying a current i , equal to 5A is placed in the plane of paper as shown in figure. Force acting on the wire (in Newton) is

An electron and proton are placed inside a uniform electric field.

An electron beam enters a magnetic field right angles to it as shown in the Figure. The direction of force acting on the electron beam will be :

A wide region of space has curved magnetic field lines as shown in the figure. A proton enters into the region as shown. Draw the path of the proton.

A proton enters a perpendicular uniform magnetic field B at origin along the positive x axis with a velocity V as shown in the figure. Then it will follow the following path. [The magnetic field is directed into the paper]

A uniform but time-varying magnetic field B(t) exists in a circular region of radius a and is directed into the plane of the paper, as shown. The magnitude of the induced electric field at point P at a distance r from the centre of the circular region
