2. Wind blowing past a flag causes it to "flutter in the breeze." The frequency of this fluttering, f, is assumed to be a function of the wind velocity, V , the air density, rho, the acceleration of gravity, g, the length of the flag, l, and the "area density" (mass per unit area) of the flag, WA. Find the appropriate Pi groups to characterize fluid mechanics phenomena that causes the fluttering.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
