Photoelectric EffectHard

Question

If the terminal speed of a gold (density = 19.5kg/m3)is 0.2m/s in a viscous liquid (density = 1.5kg/m3)find the terminal speed of a sphere of silver (denesity = 10.5kg/m3)of the same size in the same liquid

Options

A.0.4m/s
B.0.133m/s
C.0.1m/s
D.0.2m/s

Solution

VT =
⇒ VT20.2 ×
∴ VT2 = 0.1 m/s
