please show work.

3. You wish to build a source of gravitational waves to prove that the LIGO and VIRGO detectors really work. You may assume that the detectors can observe a minimum strain of h = 10-23 at a frequency of 100 Hz. To accomplish this, you build a dumbbell with two 100 kg spheres at the end of a rigid rod that is 10 m long, and connect it to a motor so that it rotates at a frequency of 100 Hz. Using the provided approximation, give an order of magnitude estimate for the strain produced by your device in LIGO if it was at a distance of 1 m away. Hint: your answer should convince you this is a terrible idea
