Answer:
Explanation:
Be M1 and M2 the two massive objects and m the third one
The gravitational force over the third object at the beginning is zero (assuming that the position of the third object is x=0)

when the third object is displaced we have that the new position is x=Δx. Hence

I attached a scheme of the system
I hope this is useful for you

Answer: τ = 0
Explanation:
At constant angular velocity there is no angular acceleration therefore no torque.
τ = Iα
The force on a charged particle on a magnetic field is given by:

where B is the magnitude of the field, q is the charge of the particle, v is its velocity and θ is the angle between the field and the velocity of the particle.
In this case we have that:
• The magnitude of the field is 0.09 T.
,
• The charge of the particle is 3.2 x 10 –19C .
,
• The velocity is 3.0 × 10 4 m/s
,
• The angle between the field and the velocity is 90°, since they are perpendicular.
Plugging these we have:

Therefore, the force on the charge is:
Acceleration = 14/4 = ....
Given that,
Capacity = 3.6 gallons per minutes
Convert it into milliliters per seconds
Since, 1 gallon = 3.79 liters
1 liters = 1000 milliliters
Capacity= (3.6*3.79*1000)/(60)
Capacity = 227.4 milliliters per second.
