1. Two particles have equal masses of 5.0 g each and opposite charges of +4.0 X 10-5 C and -4.0 X 10-5C. They are released from rest with a separation of 1.0 m between them. Find the speeds of the particles when the separation is reduced to 50 cm.
3. Consider a uniformly charged ring of radius R. Find the point on the axis where the electric field is maximum.
4. A circular wire-loop of radius 'a' carries a total charge Q distributed uniformly over its length. A small length dL of the wire is cut off. Find the electric field at the centre due to the remaining wire.
5. Positive charge Q is distributed uniformly along the positive y-axis between y=0 and y=a. A negative point charge -q lies on the positive x-axis, a distance x from the origin (a) Calculate the x- and y-components of the electric field produced by the charge distribution Q at points on the positive x-axis. (b) Calculate the x- and y- components of the force that the charge distribution Q exerts on q.
6. Positive charge Q is uniformly distributed around a semicircle of radius a. Find the electric field (magnitude and direction) at the center of curvature P.
7. A small sphere with mass m carries a positive charge q and is attached to one end of a silk fiber of length L. The other end of the fiber is attached to a large vertical insulating sheet that has a positive surface charge density a. when the sphere is in equilibrium. At what angle the fiber makes with the vertical sheet.
Find the surface area that portion of the surface y2 + z2 = a2 that lies inside the surface x2 + y2 = a2

Evaluate the integrals - In = 0∫π sin(nx)/sin(x) dx and Jn = 0∫π(sin(nx)/sin(x))2 dx, for n = 1, 2, 3 . . . .
We know that F(x) = 0∫xee^t dt is a continuous function by FTC1, though it is not an elementary function. The functions are not elementary either, but they can be expressed in terms of F. Evaluate the following integrals in terms of F.
