A small block with mass $0\mathrm{.}0500$ kg slides in a vertical circle of radius R $=0\mathrm{.}150$ m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block$$s path, the normal force the track exerts on the block has magnitude $3\mathrm{.}50$ N$.$ What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path? $($Take g $=10\mathrm{.}0$ m$/$s$2.)($a$)1\mathrm{.}00$ N $($b$)0\mathrm{.}500$ N $($c$)23$ N $($d$)3$ N $($e$)0\mathrm{.}0500$ N
