If the extension of the spring with the unknown blue mass is 12 cm, determine the value of the load (in kg). Use the spring constant determined in the previous answer. Use the gravitational constant as 10 m/s_squared. Give only the number as an
answer, do not include the unit when entering the number in the block below

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)
