Answer:
diameter = 9.951 × 
m
Explanation:
given data
NA = 0.1
refractive index = 1.465
wavelength = 1.3 μm
to find out
What is the largest core diameter for which the fiber remains single-mode
solution
we know that for single mode v number is
V ≤ 2.405
and v = 
here r is radius
so we can say
= 2.405
put here value
= 2.405
solve it we get r
r = 4.975979 × 
m
so diameter is = 2 × 4.975979 × m
diameter = 9.951 × m

Elastic potential energy = force x distance of displacement.
Explanation:
Answer:
B. to the right
Explanation:
Given:
- distance of the test charge from +Q, r
- distance of test charge from +2Q, 2r
<u>Force on the test charge due to +Q:</u>
<u>Force on the test charge due to +Q:</u>
Since all the charges are positive here, so they will try to repel the test charge away. And the force due to charge +Q will be greater so initially the test charge will move rightwards away from the +Q charge.
