The density P of a spherical ball of diameter d... - WAEC Physics 2011 Question
The density P of a spherical ball of diameter d and mass m is given by
A
P = \(\frac{3m}{4 \pi d^3}\)
B
p = 4\(\pi md^3\)
C
p = \(\frac{6m}{\pi d^3}\)
D
p = \(\frac{3m}{2 \pi d^3}\)
correct option: c
p = \(\frac{M}{V} = \frac{M}{\frac{4}{3} \pi (\frac{d}{\pi})^3}\)
= \(\frac{6m}{\pi d^3}\)
= \(\frac{6m}{\pi d^3}\)
