Three positive charges are arranged as shown in the diagram. what is the magnitude and direction of the net electrical force acting on the +3 µc charge? magnitude: 1.75 n direction: 6.2° north of east magnitude: 1.75 n direction: 6.2° south of east magnitude: 1.86 n direction: 21° north of east magnitude: 1.86 n direction: 21° south of east

magnitude: 1.75 N direction: 6.2° north of east

The Coulomb force equation is, where, is force on 1 due to 2, k is coulomb constant, are the charges and r is the distance between the charges 1 and 2.

The magnitude of force on 3 from 5 is,

The magnitude of force on 3 from 9 is,

The resultant magnitude is,

The Force from 9 on 3 is large which is in northeast direction so the resultant force will also be in north east direction only. So, 6.2 ° North of east.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

i think its c if i'm wrong
