Acharge q = 2.00 μc is placed at the origin in a region where there is already a uniform electric field = (100 n/c) î. calculate the flux of the net electric field through a gaussian sphere of radius r = 10.0 cm centered at the origin. (ε0 = 8.85 × 10-12 c2/n ∙ m2)

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
