A small block with mass $0\mathrm{.}200$ kg is attached to one end of a light rope and is swung in a vertical circle while the other end of the rope is held stationary. The length of the rope is $1\mathrm{.}20$ m$.$ When the block is at the top of its vertical path its speed is $5\mathrm{.}00$ m$/$s$.$ When the block is at this point what is the tension in the vertical rope? $5$ m$/$s $($a$)6\mathrm{.}1$ N $($b$)4\mathrm{.}2$ N $($c$)2\mathrm{.}2$ N $($d$)2\mathrm{.}0$ N $($e$)$ none of the above answers
