2. Four charged particles are placed so that each particle is at the corner of a square. The sides of the square are 17cm. The charge at the upper left corner is +3°C, the charge at the
upper right corner is -6uc, the charge at the lower left corner is -2.4°C, and the charge on
the lower right corner is -9uc.
What is the net electric force on the +3C charge?

it should be all of them because it asks if you included all of those in your answer

explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
