i need the answer quickly

A force F, (=20 N) is applied on an area A
(=0.1 cm-) at the surface of a fluid element in the outward
direction. The force , acts at an angle of 601 from the
tangential plane at the point of application of the force.
Another force I, (60 N) is applied in the same manner as
the fore F,. on an another area 4, (=0.2 cm-) at the surface
of the same fluid element. The ratio of the normal stress at
area 1, to the shear stress at årea 1, is
(A) 2:3
(B) 2:3/3
(C) 2:/3
(D) 13
