makes an angle of 135 degrees relative to the positive x direction

makes an angle of 45 degrees relative to the positive x direction

points in the positive y direction

points in the negative y direction

Answer #1

Question 1

The force exerted by the first proton on the third proton will have a vertical component along the Y-axis, and a horizontal component along the negative X-axis.The force exerted by the second proton on the third proton will have a vertical component along the Y-axis, and a horizontal component along the positive X-axis. The horizontanl component of each will cancel out, being oppposite in sign, while the component along the Y-axis will add up. Hence , the final force will point in the positive Y-direction.

The third option is correct.

Question 2

The potential at the spot under consideration will be positive, as it is due to two positive charges. Since potential energy is given by , the potential of the negatively charged electron will be negative.

The fourth option is correct.
