Question 1 Report
Particles of mass 10-2kg is fixed to the tip of a fan blade which rotates with angular velocity of 100rad-1. If the radius of the blade is 0.2m, the centripetal force is
Answer Details
The centripetal force is the force that keeps an object moving in a circular path. It is given by the formula F = mrω^2, where F is the centripetal force, m is the mass of the object, r is the radius of the circular path, and ω is the angular velocity of the object.
In this case, the mass of the particles is 10^-2 kg, the radius of the blade is 0.2m, and the angular velocity of the blade is 100 rad^-1. Plugging these values into the formula, we get:
F = (10^-2 kg)(0.2 m)(100 rad^-1)^2
= 20 N
Therefore, the centripetal force is 20 N.
