Q1. A cylindrical container with a cross-sectional area of 65.2 cm^2 holds the fluid of density 846 kg/m^3. At the bottom of the container the pressure is 116 kPa. What is the depth of fluid? Find out the pressure at the bottom of the container after an additional 2.25 x 10^-3 m^3 of this fluid is added to this container. Presume that no fluid spills out of the container.

Q2. Two charged Ping-Pong balls separated by the distance of 1.62 m exert an electric force of 0.0234N on each other. What will be the force if the objects are brought closer, to a separation of only 31.4 cm?
