Calculate the force output by the larger piston of a hydraulic lift when a force of 700 n is exerted on the smaller piston. the areas of the two pistons are 20cm squared and 950 cm squared

Could someone . i have tried to solve myself but my calculation is off

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
