**(c)**

Here,

Let = area of cross-section of each hole

density of the liquid

The momentum of the liquid flowing out per second through lower hole mass velocity

The force exerted on the lower hole towards left

Similarly, the force exerted on the upper hole towards right

Net force on the tank,
