WIll someone please solve 10F for me please!
A ball with charge q = 10.4 mu C and mass m = 0.075 kg is hung down from the ceiling by a string with length L = 2 m. A uniform electric field E perpendicular to the string with a magnitude of 500 V/m is applied to the ball-string system. The ball then begins to move. Ignore the air resistance. Suppose point B is the highest point the ball can reach. Take theta as the angle of the string with the vertical direction at point B. Write the equation of the change of the gravitational potential energy Delta U_g from point A to point B in terms of symbols given. What's the change of the electrical potential energy Delta U_e from point A to point B in terms of symbols given? Select the correct equation of angle theta based on equations in Part (a) and Part (b). Solve for the numerical value of theta. The units of theta are degrees. Suppose point C is the point where the ball reaches its highest velocity, and a is the angle of the string at point C. Which of the free body diagrams below for the ball is correct? Write an equation for the sum of forces in the direction of motion of the ball when it is at location C. Assume counterclockwise is positive.Explanation / Answer
