The magnitude of net buoyant force in the liquid will be 1.029 N.

Whenever an object is submerged into water, the water exerts a force on an object in the upward direction. When an object push water, water pushes it back with more force. Basically buoyant force is the weight of fluid displaced by the object submerged in water.

B = weight of object in air - weight of object in water

Converting gram into N

We know that 1 kg = 9.8 N

Changing kg into gram by multiplying both sides with 1x10¯³

1 g = 9.8x10¯³ N

400 g = 400x9.8x10¯³N

400 g = 4.214 N

354.5 g = 354.5x9. 8x10¯³ N

354.5 g = 3.185 N

Now, finding buoyant force

B = weight of object in air - weight of object in water

B = 4.214 - 3.185

B = 1.029 N

Therefore the magnitude of net buoyant force in the liquid will be 1.029 N.
