The electric field near the surface of Earth points downward and has a magnitude of 152 N/C. What is the ratio of the magnitude of the upward electric force on an electron to the magnitude of gravitational force on the electron? What charge should be placed on a plastic ball of mass 4.06 g so that the electric force balances the weight of the ball near Earth's surface?
The electric field near the surface of Earth points downward and has a magnitude of 148 N/C. What is the ratio of the magnitude of the upward electric force on an electron to the magnitude of gravitational force on the electron? Problem 21-40b: What charge should be placed on a plastic ball of mass 5.38 g so that the electric force balances the weight of the ball near Earth's surface?
The electric field near the surface of Earth points downward and has a magnitude of 148 N/C. What is the ratio of the magnitude of the upward electric force on an electron to the magnitude of gravitational force on the electron? Tries 0/5 Problem 21-40b: What charge should be placed on a plastic ball of mass 5.38 g so that the electric force balances the weight of the ball near Earth's surface?
Under normal atmospheric conditions, there exists a weak electric field near the earth's surface, pointing vertically downward, whose value is 150 N/C. Find the necessary charge on a 2.70 gram ping-pong ball so that the ball could levitate' in this field. In other words, the upward electrical force would just balance the downward gravitational force. Would the acquired charge need to be positive or negative?
