Problem 82P

CP Two tiny spheres of mass 6.80 mg carry charges of equal magnitude, 72.0 nC, but opposite sign. They are tied to the same ceiling hook by light strings of length 0.530 m. When a horizontal uniform electric field E that is directed to the left is turned on, the spheres hang at rest with the angle between the strings equal to 58.0° (Fig. P21.74). (a) Which ball (the one on the right or the one on the left) has positive charge? (b) What is the magnitude E of the field?

LECTURE 03/28/17 Hubble’s Law - Formulated by Edwin Hubble (1929)  Recessional Velocity is proportional to the distance Mag 6 - Naked Eye Limit Apparent Magnitude and Absolute Magnitude (Distance = 10 Pc): M = m + 5 - 5logD Where  M = Absolute Magnitude - A measure of the true brightness of a star.  m = Apparent Magnitude - How bright a star appears in the night sky  D = Distance to the star in Parsecs (Pc) E.g. for a star which is 10 Parsecs away, M = m. V is calculated via Redshift
