Question

a body moves on a circular path of radius 3 metre it completes 3 and half rounds in 12 seconds find the displacement of the body​

Answer 1

$\huge\underline\blue{\sf Answer:}$

$\large\red{\boxed{\sf Displacement(s)=6\:m}}$

$\huge\underline\blue{\sf Solution:}$

$\large\underline\pink{\sf Given:}$

• Radius (r) = 3m

• Revolution = $\sf{3{\frac{1}{2}}}$

• Time (t) = 12 sec

$\large\underline\pink{\sf To\:Find:}$

• Displacement of body (s) = ?

____________________________________

Now as we know ,

Displacement :- It is shortest distance travelled by the object/person.

Therefore  here in this question

shortest distance travelled by body is equal to the diameter of the circular path .

Displacement (s) = 2r

$\large\implies{\sf s = 2 \times 3}$

$\large\implies{\sf s = 6\:m}$

$\huge\red{♡}$$\large\red{\boxed{\sf Displacement(s)=6\:m}}$

Answer 2

Answer:

as the displacement D=2r

Explanation: the radius given=3m then as per the formula D=2x3 =6m
