1. Two oxide ions (net charge of -2e) are fixed in place at a distance of 50.0 um away from each other. a. What is the magnitude and direction of the field at a point p between the ions, located 10 pm
from the ion on the left?
b. Find the force that would be exerted on an electron if it were to be placed at point P. (Be sure to
include the direction of the force.)

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
