A colom of water 10 feet tall exert a pressure of pound at the bottom

If 2.31 feet of water =0.433 pressure

Then 10 feet of water = x

Therefore, x= 10/0.433*2.31

=53.3

I hope this helps

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

i think the answer would be reserve.
