Since both of them have equal accelaration downwards (9.8m/s²) , from perspective of one, the other has no accelaration. So they will only have a relative velocity wrt each other, hence one will see another moving in a straight line.
Note the relative velocity might as well be zero, for example when both are thrown simultaneously with identical velocities. So they might be in rest wrt each other. That's just a special case of straight line

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
