Question

A uniform rod of length 2.0 m is suspended through an end and is set oscillating with small amplitude. The time period is approximately –

• A. 1.60 s
• B. 1.80 s
• C. 2.00 s
• D. 2.40 s

Answer 1

Answer: (D)

2.40 s

Answer 2

T = 2p$\sqrt { \frac { \mathrm { I } _ { 0 } + \mathrm { m } \ell _ { 1 } ^ { 2 } } { \mathrm { mg } \ell _ { 1 } } }$

= 2pPut l = 2m, g = 9.81 m/s²

\ T = 2.40 s
