A charge q moves region in a electric field E and the magnetic field B both exist, then the force on its is: (1.)q ( v × B ) (2.)q E + q ( v × B ) (3.)q B + q ( B × v ) (4.)q B + q ( B × v )

A particle having charge q moves with a velocity v through a region in which both an electric field vecE and a magnetic field B are present. The force on the particle is

Assertion If the path of a charged particle in a region of uniform electric and magnetic field is not a circle, then its kinetic energy may remain constant. Reason In a combined electric and magnetic field region a moving charge experiences a net force F=qE+q(VxxB), where symbols have their usual meanings.

A charge particle travels along a straight line with a speed v in region where both electric field E and magnetic field b are present.It follows that

In a region where both non-zero uniform electric field and magnetic field coexist, the path of a charged particle

Statement (A) : Moving charges produce not only an electric field but also magnetic field in space Statement (B) : The force is exerted by a magnetic field on moving charges or on a current carrying conductor only but not on stationary charges

(a) Write the expression for the force, vecF , acting on a charged particle of charge 'q', moving with a velocity vecV in the presence of both electric field vecE and magnetic field vecB . Obtain the condition under which the particle moves undeflected through the fields. (b) A rectangular loop of size lxxb carrying a steady current I is placed in a uniform magnetic field vecB . Prove that the torque vectau acting on the loop is given by vectau=vecmxxvecB," where "vecm is the magnetic moment of the loop.
