The direction of force, when electric current and magnetic field direction given is at 90° to the plane containing current I and Magnetic field B.
<h3>What is magnetic force?</h3>
The force of attraction or repulsion experienced by a magnetic material when it enters the magnetic field.
When a wire with an electric current I is placed in a magnetic field of strength B it experiences a magnetic force F.
According to the Fleming's right hand rule, the direction can be determined by knowing any two parameter's direction.
Thus, The direction of force is at 90° to the plane containing current I and Magnetic field B.

Question:
Consider a sample of helium gas in a container fitted with a piston as pictured below. The piston is frictionless, but has a mass of 10.0 kg. How many of the following processes will cause the piston to move away from the base and decrease the pressure of the gas? Assume ideal behavior.
I. Heating the helium. II.
II. toRemoving some of the helium from the container.
III. Turning the container on its side.
IV. Decreasing the pressure outside the container.
a) 0
b) 1
c) 2
d) 3
e) 4
Answer:
Only one process will cause the piston to move which is
i) Heating the helium
Explanation:
When helium is heated it becomes less dense or lighter. Heating the helium will cause an increase in volume which will make the piston to move away from the base. When the volume finishes increasing, the piston will stop moving which in turn will make the forces on both sides of the piston balanced, so the pressure inside will balance the weight of the piston and that of the atmosphere. From that we can see that there has been a pressure change as a result of heating.
Rain is considered a precipitate. Along with: drizzle, sleet, snow and hail.

As per Newton's III law we can say that
Force applied by object 1 on object 2 is always equal in magnitude and opposite in direction of the force that object 2 apply on object 1.
So we can say it as
now here above question is based upon the same
if a bag of vegetables applied a force F = 22.5 N of the surface stand the the same surface will apply same magnitude of force in opposite direction on the vegetables bag
So our answer will be F = 22.5 N (upwards).
