Three of your friends are pulling a object placed
on ground with forces shown in diagram. When
they are unable to pull the object, they call you for
help. Instead of pulling the object directly, you
start calculating the minimum net force required
to move the object. (May be you are intelligent,
may be you are lazy). You find that minimum net
force required in any direction should be 60 N.
The minimum force (in newton) you should apply
to move the object is. (Assume that your friends
are still applying force in the earlier directions).

= 2 2 17 14 +
= 485 = 22.0222
Resultant of force applied by three friend
is 22.022 N. To move object force required
is 60N so force applied by you is
= 60 – 22.022 = 37.977 » 38 W
38N is minmum force need to applied to move object
Explanation:
There are three forces
20N
in x direction = 0 & in y direction = 20 N
10N
in x direction = 10Cos37° = 8N & in y direction = 10Sin37° = 6 N
15N
in x direction = 15Cos53° = 9N & in y direction = -15Sin53° = -12 N
Net Force in x direction = 0 + 8 + 9 = 17N
Net force in y Direction = 20 + 6 - 12 = 14N
Resultant Force = √17² + 14² = 22N
minimum net force required in any direction should be 60 N.
The minimum force (in newton) you should apply to move the object =60 - 22 = 38N
38N is minimum force need to applied to move object
