Question 11 2 pts A small sphere with a mass of 441 g is moving upward along the vertical +y-axis when it encounters an electric field of 5.00 N/C 2. If, due to this field, the sphere suddenly acquires a horizontal acceleration of 13.0 m/s?, what is the charge that it carries? 1150 C O -1.15 C -1150 C none of the given choices O 1.15 CQuestion 13 2 pts A metal sphere of radius 10 cm carries a charge of +2.0 uC uniformly distributed over its surface. What is the magnitude of the electric field due to this sphere at a point 5.0 cm outside the sphere's surface? (k = 1/4neg - 8.99 x 10 N - m2/c2) O 4.0 * 105 N/C O 8.0 x 10/ N/C O 4.0 x 10/ N/C 8.0 * 105 N/C O none of the given choicesQuestion 15 2 pts Two tiny particles having charges +20.0 uC and -8.00 uC are separated by a distance of 20.0 cm. What are the magnitude and direction of the electric field midway between these two charges? (k = 1/4neg = 9.0 x 109 N - m2/c2) O 25.2 x 10% N/C directed towards the negative charge 25.2 x 10 N/C directed towards the negative charge O 25.2 x 10 N/C directed towards the positive charge 25.2 x 10 N/C directed towards the positive charge O none of the given choicesQuestion 12 2 pts In the figure, all the charges are point charges and the charge in the middle is (--3.1 nC. For what charge q1 will charge q2 be in static equilibrium? 10 em O none of the given choices 12 nC O 3.1 nc O 25 nC 6.2 ncQuestion 14 2 pts The figure shows two tiny 5.0-g spheres suspended from two very thin 1.0-m-long threads. The spheres repel each other after being charged to +91 nc and hang at rest as shown. What is the angle 0? (k = 1/4neg - 8.99 x 109 N . m2/c2) 1.0 m + 50 . O 4.1' O 16' O 8.2" 12' O none of the given choices
