A cylindrical rod of length 1 m and radius 4 cm is mounted vertically. It is subjected to a shear force of

10^5 \mathrm{~N}

at the top. Considering infinitesimally small displacement in the upper edge, the angular displacement

\theta

of the rod axis from its original position would be : (shear moduli,

G=10^{10} \mathrm{~N} / \mathrm{m}^2

)

A
$1 / 160 \pi$
B
$1 / 2 \pi$
C
$1 / 4 \pi$
D
$1 / 40 \pi$
