A positively charged rod touches the wire of the electroscope and the leaves move apart. Then a negatively charged rod is brought close (but not touching) to the electroscope and the leaves move towards each other. Why? Are the leaves charged?

There is a line of negative charge (-Q) along the y axis (from 0 to L)....

There is a line of negative charge (-Q) along the y axis (from 0 to L). There is a line of positive charge (+Q) along the x-axis (from 0 to L). A) Find the electric field at the point (L/2, L/2). Sketch the direction of the field at this point on a diagram of the situation. B) Find the potential at the point (L/2, L/2).

We have a metal rod of length L. The rod is on the x-axis extending from 0 to L. We select a point X on the rod randomly and uniformly and cut the rod at X. This gives two smaller rods of lengths X and L − X. We select the longer piece (if the two pieces are of equal length we select one of them) and cut it again randomly and uniformly to get three pieces. What is the...

A ladder of unit length leans against a wall (y-axis) as its bottom slides along the ground (x-axis). As the ladder slides from vertical to horizontal, one end remains in contact with the wall while the other end remains in contact with the ground. Find : (1) Derive an algebraic equation describing the trajectory traced out by the midpoint of the ladder. What is the shape of the trajectory? (2) Derive an algebraic equation for the envelope bounded by the...

Two uncharged conducting spheres supported by insulated stands are placed in contact. A positively charged rod is brought close to one of the spheres on the side opposite from the other sphere. (a)Describe the induced charges on the spheres, and sketch the charge distributions on them. (b)The two spheres are moved far away from each other and then the charged rod is removed. Sketch the charge distributions on the spheres. (c)Describe what would have happened if the charged rod had...

A 5.0 kg rod with a length of 2.8 m has an axis of rotation at its center. Looking at the rod with its axis perpendicular to this page, a force of 14.5 N at 68o is applied to the rod 1.1 m from the axis of rotation. This torque would angularly accelerate the rod in a counter-clockwise direction. Assume that the torque continues to be applied during the motion consider in this problem and that there are no other...
