No; electromagnetic force is the force created by an electrical current attached to a magnet
The displacement of end a is 1.09mm
given:
Rod diameter,d=20mm
stiffness constant,k=55mn/m
force,f=60kn
young modulus,E= 200gpa
we know the formula
By substituting values in the above formula
length L=A×E/K
=1.14m
Hence, displacement is
=1.09mm

Answer:
x = 3 cm
Explanation:
Given that,
The separation between the slits,
The distance from the slits to a screen, D = 2.5 m
Let x is the spacing between the first-order and second-order bright fringes when coherent light of wavelength 600 nm illuminates the slits,
We know that the bright fringe is given by :
So, the spacing between the first-order and second-order bright fringes is :
x = 0.03 m
or
x = 3 cm
So, the spacing between the first-order and second-order bright fringes is 3 cm. Hence, this is the required solution.
