Calculate the force \( F \) that is applied horizontally at the axle of the wheel which is necessary to raise the wheel over the obstacle of height \( 0.4 \) \( \mathrm{m} \). Radius of wheel is \( 1 \mathrm{~m} \) and mass \( =10 \mathrm{~kg} \cdot F \) is
(1) \( 100 \mathrm{~N} \)
(2) \( 66 \mathrm{~N} \)
(3) \( 167 \mathrm{~N} \)
(4) \( 133.3 \mathrm{~N} \)
