An engineer turns a nut by applying a constant force to a $25.00\ \mathrm{cm}$ spanner. They applied this force at different angles and measured the torque. The graph shows the data collected by the engineer.

What is the magnitude of the force applied to the nut?
(A) $14.8\ \mathrm{N}$
(B) $84.8\ \mathrm{N}$
(C) $339\ \mathrm{N}$
(D) $1333\ \mathrm{N}$
