Answer:
B on edge
Explanation:
the piles of the magnetic field generated around the armature are attracted to the opposite poles of the permanent magnent. As the opposite poles align, the commutator reverses the current direction so like poles are aligned and the armature continues to spin
For the answer to the question above, we have to use this formula
Pressure = P = force / area
Then, just substitute the values of the formula
force = mg = 2(10) = 20 N
area = A = 1 cm² = [1 x 10 ̄ ²]² m²
=> P = 20 N / [1 x 10 ̄ ²]² = 200 x 10³ Pa
= 200 kPa
I hope my answer helped you. Have a nice day!
