Calculate the perimeter of given in HCP ...

Calculate the perimeter of given in `HCP` unit cell `(` Given that radius of atoms `=RÅ)`.

A

6.437R

B

15.32R

C

16R

D

8R

Text Solution

Verified by Experts

The correct Answer is:
A
Perimeter of place is `= 2C + 8R = (2 xx 4 sqrt2R)/(3) + 8R = 6.437 R`
