PhysicsSingle correct+4 / -1Question 44 of 90

Given below are two statements :

Statement I: The electric force changes the speed of the charged particle and hence changes its kinetic energy; whereas the magnetic force does not change the kinetic energy of the charged particle.

Statement II: The electric force accelerates the positively charged particle perpendicular to the direction of electric field. The magnetic force accelerates the moving charged particle along the direction of magnetic field.

In the light of the above statements, choose the most appropriate answer from the options given below :

Both Statement I and Statement II are correct.

Both Statement I and Statement II are incorrect.

Statement I is correct but Statement II is incorrect.

Statement I is incorrect but Statement II is correct.

Answer and worked solution

Official answer: C

Statement I true: the magnetic force is perpendicular to velocity and does no work. Statement II false: the electric force is along the field, and the magnetic force is perpendicular to the field.

(C)
