Solution - Winding Spring | Collection of Physics Problems

http://collectionofphysicsproblems.blogspot.com/2003/03/solution-winding-spring.html

Swinging Ball on Rough Inclined Plane. Solution - Winding Spring. Assume the spring consists of N. Small springs, where N 1. Hence, relaxed length of the small spring is. The large spring equals to the small springs in series, so. From the equation above, we can conclude that multiply between spring constant of a part and its relaxed length is constant. And we can write. Differentiate it, and we get. The total length of unwinding spring is L. If the cylinder rotates by small angle. And give torque,.

Solution - Leak Charge | Collection of Physics Problems

http://collectionofphysicsproblems.blogspot.com/2003/03/solution-leak-charge.html

Swinging Ball on Rough Inclined Plane. Solution - Leak Charge. The ball is a conductor, so all of the charge is on its surface. The electrical field on its surface is. Because it's placed inside a material with conductivity σ. The current density on its surface is. Hence, the total current flow out from the ball is. The current equals to the decreasing rate of charge. Integrate both sides of the equation. If you have any question, correction, or comment, please leave a comment below. Say {E} is electrica...
