Rotational Motion Question 178
Question: A wheel of radius 0.lm (wheel A) is attached by a non-stretching belt to a wheel of radius 0.2m (wheel B). The belt does not slip. By the time wheel B turns through 1 revolution, wheel A will rotate through
Options:
A) $\frac{1}{2}$ revolution
B) 1 revolution
C) 2 revolution
D) 4 revolution
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Let speed of belt be v Angular speeds of wheels
$ \omega_B=\frac{v}{2 \pi R_B}, \omega_A=\frac{v}{2 \pi R_A} ; \frac{\omega_A}{\omega_B}=\frac{R_B}{R_A}=2 $
