Answer:
Second object is located at 42.03 cm in front of mirror
Explanation:
In this question we have given,
object distance from convex mirror ,u=-13.5cm
Image distance from convex mirror,v=7.05cm
let focal length of convex mirror be f
we have to find the distance of second object from convex mirror
we know that u, v and f are related by following formula
.............(1)
put values of u and v in equation (1)
we got,
we have given that
second object is twice as tall as the first object
and image height of both objects are same
it means
.............(2)
we know that
therefore,
.................(3)
put values of v and u in equation 3
therefore from equation 2
we know that
.................(4)
put value of and
in equation 4
we know that U,V and f are related by following formula
.............(5)
put values of f and U in equation 5
we got
Therefore,
U=-10.91\times 3.85
U=-42.03 cm
Second object is located at 42.03 cm in front of mirror
Answer:
Part a)
Induced EMF when length vector is along Z direction is 0.72 V
Part b)
Induced EMF when length vector is along Y direction is ZERO
Explanation:
As we know that the motional EMF induced in the wire is given as
1)
As we know that
now we have
so we have
2)
If the length vector is along Y direction then we have
so again we have
so we have
EMF = 0
