Name the different apparatus where we are using the convex and concave
lenses.
8. Write the four quantum numbers for the differentiating electron of sodium (Na
atom).
9. What is the magnetic force on moving charge when there is an angle θ between
Answers
Answer:
7)concave lenses are used for correcting myopia and convex lenses are used for correcting hypermetropia.
concave lenses are used in a variety of technical and scientific products.
convex lenses are used in binoculars and telescope.
8)Sodium (Na) Z= 11
electronic configuration 1s2 2s2 2p6 3s1
the differentiating electron is in 3s
the four quantum number is
n - 3
l - 0
m - 0
s - 1/2
9)The direction of the magnetic force on a moving charge is perpendicular to the plane formed by v and B and follows right hand rule–1 (RHR-1) as shown. The magnitude of the force is proportional to q, v, B, and the sine of the angle between v and B.
