The diagram shows four locations in the electric field of a positive point charge. A positively charged particle has vectors perpendicular to the surface and pointing laterally outward. The vectors farther from the surface are shorter. There are 4 dots to the right of the positively charged particle. The closest to the particle is labeled W and the particles further away are labeled X, Y and Z.

At which point is the electric potential the greatest?

W

X

Y

Z

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
