Particles q1, 92, and q3 are in a straight line. Particles q1 = -28.1 uc, q2 = +25.5 uc, and 43 = -47.9 uc. Particles qı and q2 are separated by 0.300 m. Particles q2 and q3 are separated by 0.300 m. What is the net force on q3?​

Why do different substances have diffrent properties

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)
