5. Assertion (A): A proton is placed in a uniform electric field, it tend to move along thedirection of electric field.Reason(R): A proton is placed in a uniform electric field it experiences a force.

A proton and an electron are placed in a uniform electric field :-The magnitude of the electric force acting on them will be equal.The electric force acting on them will be equal.The magnitude of their acceleration will be equal.Their acceleration will be equal.

A proton moving with a constant velocity passes through a region of space without any change in its velocity. If   and  represent the electric and magnetic fields respectively,. then this region of space may have :-(i) E = 0, B = 0     (ii) E = 0, B ≠ 0(iii) E ≠ 0, B = 0    (iv) E ≠ 0, B ≠ 0Correct statements are –i, ii and iiiii, iii and ivi, ii and iv All

Beams of electrons and protons move parallel to each other in the samedirection. 'They 1(a) attract e~ch other.(b) repel each other.(c) neither attract nor repel.(d) force of attraction or repulsion depends _upon speed of

A particle of mass ‘m’ and charge ‘q’ is released from rest is a uniform electric field, the kinetic energy attained by the particle after moving a distance x is

In the presence of a uniform magnetic field, hydrogen protons1 pointLine up along the field and process around its axisAre not affected by magnetic fieldRemain oriented randomly and orient themselves in the direction of the field axisStay deflected
