7) By the right hand rule, the direction of the magnetic force on the proton is towards the right. Hence the option (A) is correct. 8) By the left hand rule for negative charges, the direction of the magnetic force will be out of the plane of the figure. Hence the option (C) is correct. 9) Since the electron is moving parallel to the direction of magnetic field hence the magnetic force is zero. 10) By the left hand rule for the negatively charged particles in magnetic field, the direction of the magnetic field should be as shown in (C) in order for the direction of force to be out of the plane.
