Four charged particles are placed so that each particle is at the corner of a square. the sides of the square are 15 cm. the charge at the upper left corner is +3.0 ? c, the charge at the upper right corner is ? 6.0 ? c, the charge at the lower left corner is ? 2.4 ? c, and the charge at the lower right corner is ? 9.0 ? c. a. what is the net electric force on the + 3.0 ? c charge? b. what is the net electric force on the ? 6.0 ? c charge? c. what is the net electric force on the ? 9.0 ? c charge?

(i) Part 1

Net force on 3 uC charge

Force due to - 6 uC

Force due to -2.4 uC charge

Force due to 9 uC charge

Now net force is given as

Part 2

Net force on -6 uC charge

Force due to 3 uC

Force due to 9 uC charge

Force due to -2.4 uC charge

Now net force is given as

PART 3

Net force on 9 uC charge

Force due to - 6 uC

Force due to -2.4 uC charge

Force due to 3 uC charge

Now net force is given as

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
