Question

3. You wish to measure how tightly an ant can hold on to its substrate. You place au
ant of mass 10 mg on a round rotating platform at a distance of 30 cm from the
centre, and begin increasing the angular velocity of the rotating platform until the
is dislodged. You find that the maximum angular velocity at which the ant can hold
on is 20 rad/s. The maximum force that the ant can exert to hold on is:
a. 0.2 mN
b. 1.2 mN
c. 0.2 N
d. 1.2 N​

Answer 1

Answer:

solved

Explanation:

a = wr² = 20 x 0.09 = 1.8 m/s²

force = ma = 0.01 × 1.8 = 18mN
