Questions
An insect trapped in a circular groove of radius 12 cm moves along the groove steadily and completes 7 revolution in 100 s. The linear speed of the insect is
detailed solution
Correct option is B
Here, r = 12 cm Frequency v = 7100HzThe angular speed of the insect isω = 2πv = 2π ×7100 = 0.44 rad s-1The linear speed of the insect isv = ωr = 0.44×12 = 5.3 cm s-1Talk to our academic expert!
