I attempted the question but it was wrong... I don't understand where i went wrong my working seems logical, can someone please help.
When a needle is gently placed on the surface of still water (γ = 0.0730 N.m-1) it can be supported by surface tension if the mass of the needle is small enough.
Calculate the maximum mass of a needle that is 4.85 cm long that can be supported by the water. Take the acceleration due to gravity to be 9.80 m/s/s.
