What two physical processes balance each other to create the condition known as gravitational equilibrium in stars?
A)the strong force and the weak force
B)the inward pull of gravity and outward pressure
C)the inward pull of gravity and surface tension
D)the strong force and the electromagnetic force

Question

Quizplus · Accepted Answer

Gravitational equilibrium is achieved when the inward pull of gravity is balanced by the outward pressure created by the heat and energy generated in the star's core. This balance between gravity and pressure maintains the stable size and shape of the star. The other options (A, C, D) do not relate to the physical processes involved in gravitational equilibrium.
