A particle of mass m and charge q has been projected from ground as shown in fig. Mark the correct statement(s) (xy) plane is vertical.

A particle of mass ma and charge q has been projected from ground as shown in fig. Mark the correct statement(s) (xy) plane is vertical.

A particle of charge q is projected from point P with velocity v as shown. Choose the correct statement from the following.

A positive charge particle of mass m and charge q is projected with velocity v as shown in Fig. If radius of curvature of charge particle in magnetic field region is greater than d, then find the time spent by the charge particle in magnetic field.

A ball of mass 1 kg is thrown up with an initial speed of 4 m//s . A second ball of mass 2 kg is released from rest from some height as shown in Fig. Choose the correct statement (s).

A particle of mass m and charge -q is projected from the origin with a horizontal speed v into an electric field of intensity E directed downward. Choose the wrong statement. Neglect gravity

A particle is having mass m & charge +q is projected horizontally from point O . Electric field is present and is directed vertically downward .

A particle of mass m carrying charge q is projected with velocity v from point P toward aninfinite line of charge from a distance a . Its speed reduces to zero momentarily at point Q , which is at a distance a//2 from the line of charge. If another particle with mass m and charge -q is projected with the same velosity v from P toward the line of charge, what will be its speed at Q ?
