Medium
1 of 1
Application

Two charged particles of same specific charge (i.e. charge per unit mass) are projected in same uniform magnetic field with projection velocities, perpendicular to the magnetic field. If the speeds of charged particles are and , then the ratio of angular speeds of the path of the particles in magnetic field will be
View answer and explanation
Correct option: A
Option A () is correct because the angular speed of a charged particle in a magnetic field depends only on the charge, magnetic field strength, and mass, not on the speed.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase
Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance The force(s) they
experience is (are) Statement-I: No 2 electric lines of force can intersect each other
Statement-II: tangent at any point of electric line of force gives the direction of electric field A force of is acting between two charges in air if the space between them is completely filled with glass , then the new force will be …… An electron is placed at centre of a conducting sphere of radius 0.2 metre having charge coulomb.
