Question

11) When a body completes one revolution in a
circular path of radius then its displacement
and distance covered are:​

Answer 1

Answer:

When the body covered one revolution of a circular path then the displacement will be zero as the object is back at its starting point on the circular path . So object is not displaced .

Now if you want to find the distance covered by the object a formula that can be used to find the distance covered by the object is 2πr which is the circumference of circle as the object walked on the boundary of circle

For example if the radius is = 14 cm then ,

Distance covered is -

$\rightarrow 2 \: \pi \: r \\ \rightarrow \: 2 \times \frac{22}{7} \times 14 \: cm \\ \rightarrow2 \times 22 \times 2 \\ \\ \rightarrow88 \: cm \: ans..$
