A spherical ball of charge has radius R and total charge Q. The electric field strength inside the ball(r ? R) is E(r)=Emax(r^(4)/R^(4)). 1) What is Emax in terms of Q and R? 2) Find an expression for the volume charge density ?(r) inside the ball as a function of r.
A non-uniformly charged sphere of radius R has a total charge Q. The electric field inside this charge distribution is described by E=Emax(r4 /R4 ), where Emax is a known constant. Using the differential form of Gauss’s law, find volume charge density as a function of r. Express your result in terms of r, R and Emax.
Please help me with this question .... Thank You ....kjdk fiksjkajkdt] skjdkjfk/sakjdktjs kijksajdf The electric field inside a charged insulated ball, with total charge, is given by 8 Ē (r) = Q 416072 where R is the radius of the ball.

Consider a charged sphere of radius R. The charge density is not constant. Rather, it blows up at the center of the sphere, but falls away exponentially fast away from the center, p(r)=(C/r2)e-kr where C is an unkown constant, and k determines how fast the charge density falls off. The total charge on the sphere is Q. a) Write down the Electric Field outside the sphere, where r ≥ R, in term of the total Q. b) Show that C=...
A conducting sphere of radius a has a total charge Q on it. A charge q is brought at a distance d from the center of the sphere (d > a). Using the method of images: (a) Find the electric potential V (r, θ) in the region r > a. (b) Find the surface charge density on the surface of the sphere. (c) Find the force on the charge q.
For a charged solid metal sphere with total charge Q and radius R centered on the origin: Select "True" or "False" for each statement. | If the solid sphere is an insulator (instead of metal) with net charge Q, the charges are wherever they were placed, and cannot move around. \/| The electric field near the metal surface on the outside is perpendicular to the surface. If the solid sphere is an insulator (instead of metal) with net charge Q,...
A uniformly charged ball of radius a and charge -Q is at the center of a hollow metal shell with inner radius b and outer radius c. The hollow sphere has a netcharge of +2Qa. determine the the electric field strength in the four regions r_<a, a<r, b_<r_<c, and r>cb. draw a graph of E versus r from r=0 to r=2c
2. (i) A uniformly charged ring has radius a- 0.15m and total charge Q 24 nC (see figure below) What is the circumference of the ring, and thus the charge per unit length (charge density) of the ring Circumference (m); charge density (C/m)
1.) Consider a spherical shell of radius R uniformly charged with a total charge of -Q. Starting at the surface of the shell going outwards, there is a uniform distribution of positive charge in a space such that the electric field at R+h vanishes, where R>>h. What is the positive charge density? Hint: We can use a binomial expansion approximation to find volume: (R + r)" = R" (1 + rR-')" ~R" (1 + nrR-1) or (R + r)" =R"...
