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