2. Draw a force diagram for the sled and kids being pulled at a constant velocity. Note that the rope pulling on the sled makes an angle with the ground that has a slope of +1/2. Label the force vectors and add coordinates to the tip of each force vector.
Set Fg sled & kids = 4 boxes.
Set the pull on the rope to go up 2 over 4

Atotal charge of –6.50 µc is uniformly distributed within a sphere that has a radius of 0.150 m. what is the magnitude and direction of the electric field at 0.300 m from the surface of the sphere? a) 2.89 × 105 n/c, radially inward b) 6.49 × 105 n/c, radially outward c) 4.69 × 105 n/c, radially inward d) 9.38 × 105 n/c, radially outward e) 1.30 × 106 n/c, radially inward
