Two rod 1 and 2 are released from rest as shown in figure . Given, `l_(1)=4l,m_(1)=2m,l_(2)=2l "and "m_(2)=m.` There is no friction between the two rods . If `alpha` be the angular acceleration of rod 1 just after the rods are released . Then,
What is the horizontal force on rod 1 by hinge. A at this instant ?

A

`((32-12sqrt(3))/(3sqrt(3))m//alpha`

B

`((16-2sqrt(3))/(sqrt(3))m//alpha`

C

`(14+2sqrt(3))m//alpha`

D
