Question

If value of acceleration due to gravity changes from one place to another, which of the following force will undergo a change?

• A. $\text{Viscous force}$
• B. $\text{Buoyant force}$
• C. $\text{Magnetic force}$
• D. $\text{All of the above}$

Answer 1

Answer: (B)

$\text{Buoyant force}$

$\text{Viscous Force depends on the viscosity between the surfaces and relative speed.}$
$\text{Magnetic Force depends on the charge and the magnetic field.}$
$\text{Buoyant Force depend on the weight of the fluid displaced which is equal to mass of fluid}$
$\text{displaced and gravity (=mg).}$
$\text{Hence if value of acceleration due to gravity changes from one place to another,}$
$\text{then it will undergo a change.}$
