A spring lies on a horizontal table, and the left end of the spring is attached to a wall. The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.77 kg, and the spring has a spring constant of 67 N/m. The coefficient of static friction between the box and the table on which it rests is ╬╝s = 0.79. Use g = 10 N/kg. What is the maximum distance x the spring can be stretched without the box moving? (Net force = 0)

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (╬╡0 = 8.85 ├Ч 10-12 c2/n ┬╖ m2)
