Question
In part (a) of the diagra, a negatively charged particle moving at a velcocity v in n evacuated space enters a region between capacitor places as shown. What direction is the E-field pointing in?
In part (b), a positively charged particle enters a sharply defined region of uniform B-field directed. What direction is the B-field pointing in?
Exam the following statments (true or false ) and explain the reason behind your conculsion.
a) the negatively charged particle in (a), on entering the electrical field between the capacitor plates, moves without change in the y-component of its velocity.
b) the negatively charged particle in (a), on entering the electrical field between the capacitor plates, moves without change in the x-component of its velocity.
c) the positively charged particle in (b), on entering the region of magnetic field , moves without change in the y-component of its velocity.
d) the positively charged particle in (b), on entering the region of magnetic field , moves without change in the x-component of its velocity.
e) Neither particle changes its speed as it continue along its trajectory.
Explanation / Answer
a). from left to right that is from positively charged plate to negatively charged plate
b).B is pointing in the downward direction going into the page
@).
a). true because the force will be in x- direction so no acceleration in y direction
b).false
as there is electric force acting in the charge in x - direction due to presence of electric field so its velocity will change
c).False
as the force will always be prependicular to its motion so there is a component in the y direction
so velocity will change
d)..False
as the force will always be prependicular to its motion so there is a component in the x direction
so velocity will change
e).False
