0.20m
0.25m
0.40m
0.50m
Correct answer is A
P = \(\frac{M}{AL}\)
L = \(\frac{M}{CA}\)
= \(\frac{1.76}{7000 \times 0.001257}\)
= 0.2m
The density P of a spherical ball of diameter d and mass m is given by
P = \(\frac{3m}{4 \pi d^3}\)
p = 4\(\pi md^3\)
p = \(\frac{6m}{\pi d^3}\)
p = \(\frac{3m}{2 \pi d^3}\)
Correct answer is C
p = \(\frac{M}{V} = \frac{M}{\frac{4}{3} \pi (\frac{d}{\pi})^3}\)
= \(\frac{6m}{\pi d^3}\)
