- A hollow conducting sphere has an inside radius of r1 = 0.17 m and an exterior radius of r2 = 0.27 m. The sphere has a net charge of Q = 5.4E-06 C. What is the field E1 in N/C 1 m from the sphere's exterior surface? What is the magnitude of the field at a distance of 0.05 m from the center of the sphere?Near its surface, the earth has an electric field that points straight down and has a magnitude of about 150 N/C. Estimate the charge that you would have to place on a basketball so that the electric force on the ball would balance its weight.A particle of mass 5.4×10^−6 g and a charge of −2 nC starts out traveling horizontallyat 500 m/s straight between two oppositely charged plates separated by 3 cm. The plateshave surface charge densities of 9 µC/m^2Determine the following:a) How long till it impacts either plate?b) How far will it travel horizontally until it impacts one of the plates?
- A charge +q is located at the origin. A charge - 2q is at 3.15 m on the x axis. (a) For what finite value of x is the electric field zero? 7 Xm To the right of both charges, which charge is always closest? Does it have the smaller or larger charge? At what locations are there two field contributions that can cancel to produce zero net field? (b) For what finite value(s) of x is the electric potential zero? x m Because the charge of -2q is closer than the charge of +q for this value of x, the 2q dominates and the total field cannot be zero. m smaller value larger valueA charged plastic ball of mass 5.00g is placed in a uniform electric field pointing vertically upwards with a strength of 300.0NC.
