A laboratory keeps a small metal cylinder marked "1.96×106 dynes" when weighed on Earth. Answer the following questions:
(i) Convert the marked value to newtons. \newline (Take 1N=105dynes.)
(ii) Using g=9.8m/s2, calculate the mass of the cylinder.
(iii) The cylinder is carried to the centre of the Earth. State and explain what its weight would be at that point.
