Physics Two identical solid pieces, one of gold and other of silver, when immersed completely in water exhibit equal weights. When weighed in air (given that density of gold is greater than that of silver) The silver piece will weigh more Both silver and gold pieces weigh equal The gold piece will weigh more Weighing will depend on their masses The silver piece will weigh more Both silver and gold pieces weigh equal The gold piece will weigh more Weighing will depend on their masses ANSWER DOWNLOAD EXAMIANS APP
