It has been proposed that a spaceship might be propelled in the solar system by radiation pressure, using a large sail made of foil. how large must the surface area of the sail be if the radiation force is to be equal in magnitude to the sun's gravitational attraction? assume that the mass of the ship + sail is 1500kg, that the sail is perfectly reflecting, and that the sail is oriented perpendicular to the sun's rays. see appendix c in your book for needed data.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
