Question

A rod is of length 2 m and of mass 1 kg. Moment of inertia about an axis perpendicular to its length and passing through one of its end is

• A. $\frac{4}{3}kg{m}^2$
• B. $\frac{1}{3}kg{m}^2$
• C. $\frac{4}{3}kg{m}^2$
• D. $\frac{3}{4}kg{m}^2$

Answer 1

The correct option is A $\frac{4}{3}kg{m}^2$

$(M.I{)}_{ro{d}_{aboutitsend}}=\frac{M{L}^2}{3}$
$=\frac{(2{)}^2.1}{3}=\frac{4}{3}kg{m}^2$
