Let C be the semicircle of radius r > 0 with center at (0, 0) and lying above the x-axis. For each x in [−r, r], let L(x) be the length of the line from (x, 0) to the semicircle C and perpendicular to the x-axis. What is the probability that L(x) is less than r/2?
a. Find the center of mass for lamina defined by the interior of
the polar curve r=sin(3) with a density
that varies according to p(r,theta)=1/r
b. Find the volume of the cylinder inside the sphere
For part a I got a mass of 2 but not sure about the x bar and y
bar calculations.
For part b Im stuck on the z bounds for the integral when doing
the problem with the cylindrical coordinate method.
We were unable to...

A line of positive charge is formed into a semicircle of radius R = 60.0 cm as shown in Figure P23.41. The charge per unit length along the semicircle is given by the expression λ = λ0cos θ. The total charge on the semicircle is 12.0 μC. Calculate the total force on a charge of 3.00 μC placed at the center of curvature P.
A line of positive charge is formed into a semicircle of radius R 80.0 cm, as shown in the figure below. The charge per unit length along the semicircle is given by the expression λ,cos(8). The total charge on the semicircle is 13.0 μC. Calculate the total force on a charge of 2.00 μC placed at the center of curvature. magnitude Poor response differs from the correct answer by more than 100%. direction upward
RC-1A charge +Q is evenly distributed around a semicircle of radius R in the x-y plane as shown to the right. a) Use dq charge elements to explain why the net field at the center of the semicircle (the origin) has no y component. Use a drawing like the one shown in your explanation. b) Apply Coulomb's law to calculate the strength (magnitude) of the net electric field at the origin in terms of K, Q, R and any other...
