A thin spherical shell of metal has a radius of 0.25 meter and carries a charge 0.2 mC. Calculate the electric intensity at a point (i) inside the shell, (ii) just outside the shell (iii) 3 m from the center of the shell. (Ans: zero ; 2.88 x 104 N/C ; 200 N/C) 4. Two large, thin metal

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

An automobile steering wheel is shown. what is the ideal mechanical advantage? if the ama is 8, what is the efficiency of the steering wheel?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
