Question

An insect moves along a circular path of radius $1\text{m}$ with a constant speed. If it takes $2$ minutes to move from a point on the path to the diametrically opposite point, then find the magnitude of the average velocity of the insect.

• A. $0.5\text{m/min}$
• B. $1.0\text{m/min}$
• C. $1.6\text{m/min}$
• D. $3.2\text{m/min}$

Answer 1

The correct option is B $1.0\text{m/min}$


Let us suppose, insect moves from point $A$ to point $B$.

We know that, average velocity,

$v=\frac{\text{Net displacement}}{\text{Total time}}$

$\Rightarrow v=\frac{2\times 1}{2}=1.0\text{m/min}$
