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.
Text Solution
Verified by ExpertsC
Statement I: It is correct, electrostatic force acts on a charged particle, its speed and K.E increased.
When a charged particle enters in a magnetic field in the same direction as that of magnetic field, it experiences no force as 
.
Statement II: It is incorrect, as electric field accelerates, the charged particle in the same direction of electric field as 
.
