Two charged particles are moving with equal velocities of 4.00 m/s in the +x-direction. at one instant of time the first particle with a charge of 7.40 μc is located at x = 0 and y = +1.60 cm, and the second particle with a charge of 3.20 μc is located at x = 0 and y = -1.60 cm.
1. what is the y-component of the magnetic force on the first particle due to the second?
2. how fast would the charges have to be moving for the magentic force to be equal in magnitude to the electric force?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
