1. The problem statement, all variables and given/known data
A biologist studying plant growth and wants to stimulate a gravitational field stronger than the Earth's. She places the plants on a horizontal rotating table in her laboratory (on Earth) at a distance of 42.3 cm from the axis of rotation. What angular speed will give the plants an effective gravitational field , geff, of magnitude 1.95 g? [Hint: Remember to account for Earth's gravitational field as well as the artificial gravity when finding the effective gravitational field.
2. Relevant equations
3. The attempt at a solution
sq rt (a/r)=w
sq rt (1.95g/.423)=w=6.72 rad/sec
This is wrong according to my text. How do i do this problem?
