Determine the magnitude of the resultant force acting on the gate abc due to hydrostatic pressure. the gate has a width of 1.5 m. rw = 1.0 mg>m3.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
