What is the electric field 3.3 m from the center of the terminal of a van de graaff with a 7.20 mc charge, noting that the field is equivalent to that of a point charge at the center of the terminal?

Electric Field is

Explanation:

Electric Field:

It originates from positive charge and ends at negative charge.

General Formula for electric Field:

where:

k is the Coulomb Constant

q is the charge

r is the distance

Given:

q=7.20 mC

r=3.3 meters

k=

Find:

Electric Field=?

Solution:

Electric Field is

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
