Dear vivek

mg force is acting on the liquid element in downward direction


and inertial force ma is acting in the apposite direction of acceleration


let F is resultant of these two


F2 =(mg)2 + (ma)2 + 2(mg)(ma)cos60


this force F makes and angel Φ with mg


tanΦ =ma sin60 /(mg + ma cos60)


   T is apposite to F


and free surface of liquid will be perpendicular to T
