A 3 kg block is acted on by a 25 N force that acts 37" below the horizontal, as shown in the Fig 1. Take Mi = 0.2 and y, = 0.5, (a) Does the block
move if it is initially at rest? (b) If it moves to the right, what is its
acceleration?

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
