Answer:
Toward the north, 300 N
Explanation:
Consider the upward direction as positive and downward direction as negative.
Given:
Mass of the balloon is, [tex]m=300\ kg[/tex]
Lift force on the balloon in the upward direction is, [tex]F_L=3300\ N[/tex]
Take acceleration due to gravity as 10 N/kg.
Now, weight of the balloon acting downward is given as the product of its mass and acceleration due to gravity. Therefore,
Weight is, [tex]W=mg=(300\ kg)(10\ N/kg)=-3000\ N[/tex]
Now, net force is given as the vector sum of both the forces.
[tex]F_{net}=F_L+W\\F_{net}=3300-3000=300\ N(\textrm{Upward direction})[/tex]
The upward direction is the direction of North. So, the net force acting on the balloon is 300 N towards North.
