Answer:
1.63 A and in clockwise direction
Explanation:
The magnetic field due to the rectangular loop is :
Given : W = 4.20 cm
L = 9.50 cm
Rearranging the above equation, we get
I = 1.63 A
So the magnitude of the current in the rectangular loop is 1.63 A.
And the direction of current is clockwise.
Answer:
t = o.6 s
Explanation:
Let ball thrown from below be A and ball dropped from above be B.
A and B meet when they both are same level above the ground. Then let A moved up a distance d and B dropped a distance h. Then you know
d + h = 15 m ---------------(1)
Now apply s = ut + at²
To A upwards,
d = 25t - gt² -----------------(2)
To B downwards,
h = 0 + gt² ----------------(3)
(1) = (2) + (3) ⇒ 15 = 25t
t = 0.6 s
