Aboy is pulling a load of 150n with a string inclined at an angle 30 to the horizontal if the tension of string is 105n the force tending to lift the load off the ground is

The force tending to lift the load (vertical force) is equal to 22.5N.

Why?

Since the boy is pulling a load (150N) with a string inclined at an angle of 30° to the horizontal, the total force will have two components (horizontal and vertical component), but we need to consider the given information about the tension of the string which is equal to 105N.

We can calculate the vertical force using the following formula:

Hence, we can see that the force tending to lift the load off the ground (vertical force) is equal to 22.5N.

Have a nice day!

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
