Help with the following please

Pressure is measured in units of Pascals, which is equivalent to kg/(m.s2). The The magnitude of the electrostatic force F between two charges Q and q, separated hydrostatic pressure in a fluid at a depth h depends only on the acceleration of by a distance ris given by: gravity (g, measured in m/s2), the density of the fluid (D, measured in units of kg/m ), and your depth (h, measured in m). If your depth in the fluid is increased by a factor F = Kq of 4, what will happen to the hydrostatic pressure? To increase the force between two charges by a factor of 4, the distance between It will decrease by a factor of 2. the charges must be: It will decrease by a factor of 4. It will decrease by a factor of 16. It will increase by a factor of 2. O increased by a factor of 2 It will increase by a factor of 4. O decreased by a factor of 2 It will increase by a factor of 16. increased by a factor of 16 O decreased by a factor of 16 The escape velocity v of a rocket from the surface of a planet of mass M and radius r is given by U = 2GM What are the units of the constant G? O kg.m O kq.m O m O m 3 kq. $2
