Small solid glass ball of radius r is irradiated by a beam of positive ions and gains a charge + q distributed uniformly throughout its volume. What is the potential (relative to infinity) at location A, inside the ball, a distance r / 6 from the center of the ball? (Use any variable or symbol stated above along with the following as necessary: ε 0 .) Give the numerical coefficient in the form of a simple fraction

V=6q/20πεor= 3q/10πεor

Step-by-step explanation:

distance between the charges is r-r/6 since the charges are located at the surface and r/6. V=w/q and W =Force X distance =kQq/r

and V = Kq/r also k =1/4πεo. Hence the potential at location A inside the ball to the charge +q at the surface is 3q/10πεor

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
