Apack of iron bolt is such that the difference in masses(weight) of successive sizes is the same. the smallest bolt being of mass 4.5g and the largest 31.5g. if the total mass is 243g, calculate
1. the number of bolts
2. the difference in the masses of successive sizes

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)
