A) 0.8 cm
B) 0.4 cm
C) 0.2 cm
D) 0.6 cm
Correct Answer: B
Solution :
Volume of 300 spherical balls = Volume of rise in water level \[\Rightarrow \]\[300\times \frac{4}{3}\times \frac{22}{7}\times {{\left( \frac{d}{2} \right)}^{3}}=\frac{22}{7}\times 2\times 2\times \frac{4}{5}\] \[\Rightarrow \]\[d=\frac{2}{5}=0.4\,cm\]
