Question

A person stands a distance R from a door's hinges and pushes with a force F directed perpendicular to its surface. By what factor does the applied torque change if the person's position and force change to 2R and F.

Solution

VerifiedStep 1

1 of 2Initial state is R and F. Final state is 2R and F. Calculating by what factor does the applied torque change:

$\dfrac{T_i}{T_f}=\dfrac{F\cdot 2R}{F\cdot 2R}=\boxed{1}$
