Three point charges lie along a straight line as shown in the figure below, where q, 6.54 pc, q 1.58 pc, and q3 3.00 cm and d, 2.00 cm. calculate the magnitude and direction of the net electric force on each of the charges. -2.14 uc. the separation distances are d (a) q1 9 magnitude nour response differs from the correct answer by more than 10 %. double check your calculations. n direction to the left (b) 2 magnitude 55 n direction to the right (c) q3 magnitude 068 to the left direction

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
