A body mass 3kg and volume 0.0004 is hung from a balance graduated in Newton's. what is the reading of the balance when the body is fully immersed in water

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

real, smaller and upside-down.   so the answer should be b.

did yall get answers for this yet
