Find the total charge inside the pyramidal cone with a square base of side 2a (-a sx s +a and -a s y s +a) and whose apex is that the point (0,0,h) if the charge density is uniform.

answer; (arch); good luck

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
