Question

A charge of -3.50 nC is placed at the origin of an xy-coordinate system, and a charge of 1.85 nC is placed on the y axis at y = 4.35 cm .

Part A

If a third charge, of 5.00 nC , is now placed at the point x = 3.25 cm , y = 4.35 cm find the x and y components of the total force exerted on this charge by the other two charges.

Express answers numerically separated by a comma.

____N

Part B

Find the magnitude of this force.

____N

Part C

Find the direction of this force.

___ degrees below the +x axis

Answer 1

As you know force between the same charge repulsive and opposite charge force will be attractive. So
