A car of mass \( =m=1000 \mathrm{~kg} \) is moving with constant speed \( v=100 \mathrm{~m} / \mathrm{s} \) on a parabolic shaped bridge \( A F O E \) of span \( l=40 \mathrm{~m} \) and height \( h=20 \mathrm{~m} \) as shown in the figure. Then the net force applied by the bridge on the car when the car is at point \( F \), is :
Figure \( 1.135 \)
(A) \( 5000 \sqrt{\frac{5}{2}} N \)
(B) \( \frac{5000}{\sqrt{2}} N \)
(C) \( \frac{10000}{\sqrt{2}} N \)
(D) \( 5000 \sqrt{\frac{2}{5}} N \)
