A point charge with charge q1 = 3.40 μC is held stationary at the origin. A second point charge with charge q2 = -4.90 μC moves from the point ( 0.125 m , 0) to the point ( 0.280 m , 0.235 m ). How much work W is done by the electric force on the moving point charge?

-0.79 J

Explanation:

We are given that

We have to find the work done by the electric force on the moving point charge.

Work done,

Where

Using the formula

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
