Question

For a body which has turned by 300° in a circle of radius r,
a. Distance travelled is 5/3pie r
b. Acceleration is constant
c. Both a. and b.
d. Only a.

Answer 1

For a body which has turned by 300° in a circle of radius r, the distance travelled is (5/3)πr

Therefore, Options (a) and (d) are correct.

Explanation:

The angle made by the body at the centre

= 300°

$=\frac{300^\circ\times \pi}{180^\circ}$

$=\frac{5\pi}{3}$ radian

Distance travelled = length of arc that substitutes angle = 300°

$=\text{Angle (in radians)\times \text{Radius}}$

$=\frac{5\pi}{3}\times r$

$=\frac{5}{3}\pi r$ unit

Since the motion of the body is non linear, the acceleration will not be constant

Therefore, correct options are (a) and (d)
