Ahydrogen atom, with its electron in the 4f state, is placed in a 1-t magnetic field. calculate the total energy spread (in units of ev) of this 4f state. ignore all spin effects

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

double the distance = divide strength by 4

v=ir = 3x15 =45 v
