Explanation:
torque on the coil is given as
where N is number of loop = 9 loops
i is current = 7.80 A
-B -earth magnetic field =
A- area of circular coil
A =0.015 m2
PUTITNG ALL VALUE TO GET TORQUE
b) north edge will rise up
Answer:
16
Explanation:
The magnitude of the electrostatic force between two charged particles is given by
where
k is the Coulomb's constant
q1, q2 are the charges of the two particles
r is the separation between the particles
In this problem, the initial force between the particles is F.
Later, the distance between the two particles is increased by four, so
r' = 4r
So, the new force between the particles will be
So, the new force decreases by a factor of 16.
