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?

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
