Common static electricity involves charges ranging from nanocoulombs to microcoulombs. 1) how many electrons are needed to form a charge of -3.50nC? 2) how many electrons much be removed from a beau real object to leave a net charge of 9.50μC?

5 a. How many electrons are needed to form a charge of Q1 = -7 nC? b. If you touch two charge balls of - 60 nC and 70 nC, what will be the net charge after touching them together?

Water has a mass per mole of 18.0 g/mol, and each water molecule (H2O) has 10 electrons.(a) How many electrons are there in 3.56 liters of water? (A liter is 1.00 10-3 m3)electrons(b) What is the net charge of all these electrons?C
