Question

If Young's modulus of iron be 2 × 1011N/m-2 and interatomic distance be 3 ×10-10m-2, the interatomic force constant will be (A) 60 N/m (B) 120 N/m (C) 30 N/m (D) 180 N/m

K = Y ro K = interatomic force constant ro =interatomic distance

Q. If Young's modulus of iron be $2 \times 1 0^{11} N / m^{- 2}$ and interatomic distance be $3 \times 1 0^{- 10} m^{- 2}$ , the interatomic force constant will be

60 N/m

120 N/m

30 N/m

180 N/m

$K = Y r_{o}$
K = interatomic force constant
$r_{o}$ =interatomic distance

Q. If Young's modulus of iron be 2×1011N/m−2 and interatomic distance be 3×10−10m−2, the interatomic force constant will be
