h = WL/4p,
h = 38.4 x 500/ ( 4 x 480).
h= 10 cm.
h = 38.4 x 500/ ( 4 x 480).
h= 10 cm.

What's the force in tendon, without it how to calculate?

Yes no force is given.
I think according to answer they should give force as 480.

wl/4
3.84 * 5 / 4 = 4.8
So, ans is 5.
3.84 * 5 / 4 = 4.8
So, ans is 5.

Which formula used for calculation?
Manikandan sivakasi said:

P*e=M.
3840*e=(load*perpendicular distance),
3840*e=(3840*5),
e=19200/3840,
e=5.
So 5 is correct answer I think.
3840*e=(load*perpendicular distance),
3840*e=(3840*5),
e=19200/3840,
e=5.
So 5 is correct answer I think.

If the load is total 3840 then how its unit is kg/m?

From where 480came? @Qasim.

Due to UDL total load will divide by 8. And 3840/8=480.
480 will be a prestressing force.
480 will be a prestressing force.

For UDL h=wl^2/8P and P should be 1200KN.
