A ▬ >E h d - As shown in the figure above, a positively charged ball is placed at point A and slides down the slope from rest. The area has a uniform electric field E = 12.9 N/C, pointing to the right. The mass of the ball is m = 9 kg and the charge is q = +2.6 C. When the ball reaches point B, it travels horizontally there after. The height from A to B is h = 37 m and the horizontal distance between A and B is d = 30 m. You can ignore friction and use g = 10 m/s for your calculation. %3D How much is the kinetic energy of the ball when it reaches at B (in the unit of J)? Submit Answer Tries 0/2 If the electric field ist changed to the opposite direction, How much is the kinetic energy of the ball when it reaches at B (in the unit of J) now? Submit Answer Tries 0/2 What is the minimum strength of electric field E that can be used to stop the particle right at Point B? N/C

Two charges, qA and qB are placed as shown in the picture below. The charges have the same absolute value, but their signs are opposite у [cm] + x [cm] An electron is placed at the origin. What is the direction of the electric force exerted on the electron due to these two charges? Assume the angle is measured counterclockwise relative to +x axis. Between 180 and 270 Between 90 and 180 Between 270 and 360 Between 0 and 90 degrees

On a typical clear day, the atmospheric electric field points downward and has a magnitude of approximately 110 N/C. Compare the gravitational and electric forces on a small dust particle of mass 3,1 x 10 g that carries a single electron charge. 1.1134 What is the acceleration (both magnitude and direction) of the dust particle? (Enter the magnitude in m/s.) magnitude m/s direction downward v

Three charges are at the corners of an equilateral triangle, as shown in the figure below. Calculate the electric field at a point midway between the two charges on the x-axis. (Let q1 = 2.50 ?C,q2 = 6.00 ?C,and q3 = −2.50 ?C.)

Three charges are located as follows along the x-axis: Q1 = +650 nC at the origin; Q2 = +330 nC at x = 2.0 cm, and Q3 = -400 nC at x = 3.0 cm. Taking positive to be to the right, calculate the electric field at the point x = 5.0 cm

Two charges, Q1 and Q2, are equal in magnitude.The electric field midway between them points from Q2 to Q1. What are the signs of the charges on Q1 and Q2, respectively?

A point charge q1 = -30.0 µC is located at r = (-2.00 m)i + (4.00 m)j + (6.00 m)k, and a point charge q2 = 40.0 µC is located at r2 = (3.00 m)i - (2.00 m)j + (1.00 m)k. Determine the magnitude of the electric force between them. %3D O 0.0857 N O 0.126 N O 0.400 N O 0.771 N
