Declare a structure to represent a circle. Each circle stores information about the center and the radius. Center is represented with x and y coordinates. Both center and radius uses doubles. Allocate an array of 50 circle pointers and dynamically allocate memory to store a circle pointed by cash array eatery. Randomly generate circles using the following function. double rand_float (double a.double b) {return ((double)rand()/RAND_MAX)=(b-a)+a:} We want all the circles to fit an area of...
please help! A charge Q is placed at the center of the square of
side 8.30cm, at the corners of which four identical charges q=7.5 C
are placed. Find the value of the charge Q so that the system is in
equilibrium.
