Answer:
When the electric force between two charged objects change, the distance between the objects increases in Iicreasing the separation distance between objects and decreases the force of attraction or repulsion between objects.
Hope it helps.
Answer:
C. It can be magnetized
Explanation:
As we know that Ferromagnetic materials are made up of small domains which can be treated as small magnets.
These small magnets are aligned in random directions so that the net magnetic field due to all small domains will cancel out and it gives no magnetic field by their own.
Now when these type of ferromagnetic substances are placed in external magnetic field then due to the external field these all domains are aligned in the direction of external magnetic field.
Due to this alignment of domains ferromagnetic substance produce their own field and this phenomenon is known as magnetization
So here correct answer will be
C. It can be magnetized
Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
