b) north edge will rise up
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:
0.49 m/s
Explanation:
The law of conservation of linear momentum states that the sum of momentum in a system before and after collision are same. Momentum is a product of mass and velocity of an object hence in this case
Where m represent mass, u and v represent the initial and final velocities respectively, subscripts c and 8 represent cue ball and number 8 ball respectively.
Since number 8 ball is initially at rest, its initial velocity is zero. Replacing mass of cue ball with 170 g while mass of number 8 ball with 160g, then taking final velocity of cue ball as 0.2 m/s and final velocity of 8 ball as 0.3 m/s then we get
