Find the magnitude of the two identical charges. -1 cm 90 N 90 N 91 Your answer Two identical charges (mass = kg) are at rest at rest on the surface of a hemispherical bowl of radius R = 0.25 m. Three forces act on each particle: the normal force, the weight force and the repulsive force they exert on each other. The normal force acting on either charge (caused by the surface of the bowl) is at 60 degrees angle to the horizontal. Find the charge on each particle. 60
