- What is the area of a sheet of paper that is 30cm long and 15cm wide?

How do you tell if someone actually cares about you? and just say they do?

What is a subatomic particle with a negative charge and very little mass?

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? (ε0 = 8.85 × 10-12 c2/n · m2)
