Acharge of +3.00 μc is located at the origin, and a second charge of -2.00 μc is located on the x-y plane at the point (50.0 cm, 60.0 cm). 1) determine the x-component of the electric force exerted by the -2.00 μc charge on the +3.00 μc charge. (express your answer to three significant figures.)

0.0567 N

Explanation:

q1 = 3 micro coulomb

q2 = - 2 micro coulomb

OB = 50 cm

AB = 60 cm

By using Pythagoras theorem in triangle OAB

OA = 78.1 cm

By using the Coulomb's law, the force on 3 micro coulomb due to -2 micro coulomb is

F = 0.0885 N

The horizontal component of force is

= F CosФ =

= 0.0885 x 50 / 78.1 = 0.0567 N

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
