Answer:
Explanation:
Wire is in the form of an arc of the size of a quarter of a circle. The distance between its two end
=√2 x 21 cm
= 29.7 cm
= 29.7 x 10⁻² m
Force on the arc in the magnetic field will be same as the straight line meeting its two ends.
Force = BIL
= 48 x10⁻³ x 1.5 x 29.7 x 10⁻²
= 2138.4 x 10⁻⁵ N.

Answer:
<h2>Angular Displacement 6.28 radians</h2>
Explanation:
for circular motion we are expected to solve for Angular Displacement it is measured in radian
Measurement of Angular Displacement.
we can measure it using the following relation
∅= s/r
where
s = the distance travelled by the body, and
r = radius of the circle along which it is moving.
given that
circumference c, s= 400 m
r= ?
we have to solve for the radius
we know that circumference

400= 2*3.142*r
400= 6.282*r
divide both sides by 6.284 we have
400/6.284
r= 63.63 m
Angular displcament
∅= 400/63.63
∅= 6.28 radians
