An electron is released from rest at a perpendicular distance of 9.1 cm from a line of charge on a very long nonconducting rod. That charge is uniformly distributed, with 7.8 ìC per meter. What is the magnitude of the electron's initial acceleration?

A ball with a mass of 4·kg is moving in a vertical circle at the end of a 0.9·m long rope. When the ball is at the top of the circle, it is going 7·m/s. What is the tension in the rope? (Again...don't need the answer...just the formula on how to find tension...already understand net force and centripetal acceleration...any help)??
