Question

the two boys are pulling the bucket by force of 10N and 20N and as a result it what rise by an angle of π/4 determine the resultant force​

Answer 1

Answer:

I'm answering it in book

F1=10N

F2=20N

resultant force=R

R= root F1²+F2²+2F1F2 Cos tita

Angle of resultant force will be force applied by first boy is 30

Tan 90= B Sin O / A+B SinO

Infinity = B Sin O / A+B SinO

A+B Cos O = 0

A= - B Cos ( not tita )

Cos (") = -A/B

= -1/2

( " ) = 120

So, R= root 30²+60²+2×30×60×Cos120

R= 51.96N

I'm ain't sure you check it again if it is
