You take an lp record out of its sleeve, and it acquires a static charge of 1 nc. you play it at the normal speed of 33r. p.m., and the charge moving in a circle creates an electric current. what is the current, in amperes? (b) although the planetary model of the atom can be made to work with any value for the radius of the electrons' orbits, more advanced models that we will study later in this course predict definite radii. if the electron is imagined as circling around the proton at a speed of 2.2 × 106 m/s, in an orbit with a radius of 0.05 nm, what electric current is created? the charge of an electron is-e =-1.60 × 10-19 c.
