Answer:
B = 8.0487mT
Explanation:
To solve the exercise it is necessary to take into account the considerations of the Magnetic Force described by Faraday,
The magnetic force is given by the formula
Where,
B = Magnetic Field
I = Current
L = Length
Angle between the magnetic field and the velocity, for this case are perpendicular, then is 90 degrees
According to our data we have that
I = 16.4A
F = 0.132N/m
As we know our equation must be modificated to Force per length unit, that is
Replacing the values we have that
Solving for B,
Answer:
Toward the north, 300 N
Explanation:
Consider the upward direction as positive and downward direction as negative.
Given:
Mass of the balloon is,
Lift force on the balloon in the upward direction is,
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,
Now, net force is given as the vector sum of both the forces.
The upward direction is the direction of North. So, the net force acting on the balloon is 300 N towards North.
