Two spherical shells have a common center. the inner shell has radius r1 = 5.00 cm and charge q1 = +5.00×10−6 c; the outer shell has radius r2 = 15.0 cm and charge q2 = −7.00×10−6 c. both charges are spread uniformly over the shell surface. take v = 0 at a large distance from the shells.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
