SOLVE THE PROBLEM 43.

Hi 043 SSM ILw www How much work is +9 -q 9* a*9 required to set up the arrangement of Fig. 24-52 if q = 2.30 pC, a = 64.0 cm, and l I the particles are initially infinitely far apart a a and at rest? I l '44 In Fig. 24-53, seven charged particles are 9' (3,0 fixed in place to form a square with an edge _q +q length of 4.0 cm. How much work must we do to bring a particle of charge +66 initially at Figure \"'52 rest from an infinite distance to the center of Problem 43- the square? y
