Chapter 20, Problem 13P

To determine

Part (a) To Determine:

direction of magnetic field on the positive charge due to magnetic force and velocity

Answer to Problem 13P

Solution:

Right

Explanation of Solution

Since velocity is inwards direction and force is in downward direction and charge is positive, so the answer is always same which is given by Fleming’s Left-Hand Thumb Rule. So direction of magnetic field is in right side.

To determine

Part (b) To Determine:

direction of magnetic field on the positive charge due to magnetic force and velocity

Answer to Problem 13P

Solution:

Downward

Explanation of Solution

Since force is in outward direction and magnetic field is in left side so force is in downward direction and charge is positive, so the answer is always same which is given by Fleming’s Left-Hand Thumb Rule.

To determine

Part (c) To Determine:

direction of magnetic field on the positive charge due to magnetic force and velocity

Answer to Problem 13P

Solution:

Into the paper

Explanation of Solution

Since direction of velocity and force are perpendicular to each other and acting along x axis and y axis respectively. According to relation,

Direction of magnetic field on a positive charge particle can be identified by using this relation,

This indicates the inwards direction perpendicular to the plane
