The Young's modulus of the material of a wire is
\( \mathrm{P} \)
\( 6 \times 10^{12} \mathrm{~N} / \mathrm{m}^{2} \) and there is no transverse strain in it,
W
then its modulus of rigidity will be
(1) \( 3 \times 10^{12} \mathrm{~N} / \mathrm{m}^{2} \)
(2) \( 2 \times 10^{12} \mathrm{~N} / \mathrm{m}^{2} \)
(3) \( 10^{12} \mathrm{~N} / \mathrm{m}^{2} \)
(4) None of the above
