Answer:
Electric field at a point ( x , y , z) is .
Explanation:
Given :
Electric potential in the region is ,
We need to find the electric field .
We know , electric field , { Here r is distance }
In coordinate system ,
{
is partial derivative }
Putting all values we get ,
Hence , this is the required solution.
Complete Question
A football coach walks 18 meters westward, then 12 meters eastward, then 28 meters westward, and finally 14 meters eastward.
a
From this motion what is the distance covered
b
What is the magnitude and direction of the displacement
Answer:
a
b
Magnitude
Direction
West
Explanation:
From the question we are told that
The first distance covered westward is
=>
=>
For the second question eastward is in the direction of the positive x-axis so it would be positive and westward is in the direction of the negative x-axis so it would be negative
The magnitude of the displacement is
=>
=>
The direction is west
