Answer:
2.1 × 10⁻⁵ T
Explanation:
Given:
Inner radius, r = 4 mm = 0.004 m
Outer radius, R = 25 mm = 0.025 m
Current, I = 4 A
Distance of the point from the center, a = 17 mm = 0.017 m
μ₀ = 4π × 10⁻⁷ T·m/A
Now,
For the hollow cylinder magnetic field (B) is given as:
on substituting the respective values, we get
or
B = 2.1 × 10⁻⁵ T
A mirror equation is an equation that relates object distance and image distance to focal length. The distance of the image from the mirror will be -3 cm.
<h3>What is a mirror equation?</h3>A mirror equation is an equation that relates object distance and image distance to focal length. It's sometimes referred to as a mirror formula.
The given data in the problem is;
f is the focal length = -4. 5 cm
u is the object distance=12. 0 cm
v is the image distance =?
Hence the distance of the image from the mirror will be -3 cm.
