A charge of 35.0 nC is placed in a uniform electric field that is directed vertically upward and that has a magnitude of 4.00 104 V/m.
(a) What work is done by the electric force when the charge moves 0.400 m to the right?
(b) What work is done by the electric force when the charge moves 0.670 m upward?
(c) What work is done by the electric force when the charge moves 2.30 m at an angle of 45.0° downward from the horizontal?
Assume all temperatures to be exact, and neglect significant figures for small changes in dimension. Concrete highway slabs are poured in lengths of 9.00m. How wide should the expansion gaps between the slabs be at a temperature of 15degreeC to ensur..
