Question

1. For a body which has turned by 300° in a circle
of radius r,
(a) distance travelled is žur
(6) acceleration is constant
(c) both (a) and (6)
(d) only (a)

plz tell fast it's urgent​

Answer 1

Answer:

both a and b

Explanation:

because instead you giving option d

it can be leave as option a itself know

Answer 2

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)

Hope this answer is helpful.
