The nuclear radius of a nucleus is proportional to the cube root of its mass number. Thus, we can use the following formula to calculate the approximate nuclear radius of 64Cu:
r(64Cu) = r(27Al) x (64(1/3))/(27(1/3))
Substituting the given values, we get:
r(64Cu) = 3.6 x (64(1/3))/(27(1/3)) r(64Cu) ≈ 4.5 Fermi
Therefore, the approximate nuclear radius of 64Cu is 4.5 Fermi.

A square loop of side 0.50 m is placed in a uniform magnetic field of 0.4 T perpendicular to the plane of the loop. The loop is rotated through an angle of $60^\circ$ in 0.2 s. The value of emf induced in the loop will be:

(II) Plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances? Explain.
