25. Electric Potential / Electric Potential Energy / Problem 12
On an unknown planet, there is an electric field of about 180 V/m directed upwards from its surface. Two similar metal spheres having mass 'm' equal to 0.75 kg are released from a height 'h' of 2.5 m above the surface. One of the spheres is negatively charged with q1 equal to -300 μC, while the other sphere is positively charged with q2 equal to +300 μC. Determine the difference in their velocities when they touch ground using principles of conservation of mechanical energy. Assume that the gravitational acceleration on the planet is 3.7 m/s2.
