Q7: Tlree forces are applied on a wheel \( \left(r=0.5 \mathrm{~m}, \mathrm{I}=0.4 \mathrm{~kg} \cdot \mathrm{m}^{2} ight) \) which can rotate about an axis perpendicular to it and passing through its center as shown. What is the magnitude of the angular acceleration (in \( \mathrm{rad} / \mathrm{s}^{2} \) ) of wheel?

Q7: Three forces are applied on a wheel (r=0.5m,I=0.4kgm2) which can rotate about an axis perpendicular to it and passing through its center as shown. What is the magnitude of the angular acceleration (in rad/s2 ) of wheel
