. The particle is given an initial horozontal velocity of
in the presence of electric field
and magnetic field
. To keep the particle moving in a horizontal direction, it is necesary that
(1) should be prependicular to the direction of velocity and
should be along the direction of velocity.
(2) Both and
should be along the direction of velocity.
(3) Both and
are mutually prependicular and prependicular to the direction of velocity.
(4) should be along the direction of velocity and
should be prependicular to the direction of velocity.
Which one of the following pairs of statements is possible?
(2) and (4)
(1) and (3)
(3) and (4)
(2) and (3)
Lorentz Force -
- wherein
Lorentz equation
For particle to move along a horizontal direction either net force is zero or force is along direction of valocity. This can happen when
either
Both and
