Apoint charge with charge q1 = 4.00 μc is held stationary at the origin. a second point charge with charge q2 = -4.40 μc moves from the point ( 0.155 m , 0) to the point ( 0.245 m , 0.270 m ). how much work w is done by the electric force on the moving point charge?

W=0.94J

Explanation:

Electrostatic potential energy is the energy that results from the position of a charge in an electric field. Therefore, the work done to move a charge from point 1 to point 2 will be the change in electrostatic potential energy between point 1 and point 2.

This energy is given by:

So, the work done to move the chargue is:

The work is positive since the potential energy in 1 is greater than 2.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

amplitude

hope this
