Answer:
Logically yes, because Newton's Third law state "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body."
If force wasn't pushing up then neither gravity is pulling down.
Answer:
12 cm
Explanation:
We shall use Lens makers formula here which is as follows
Put μ = 1.5 , R₁ = 10 cm ,R₂ = - 15 cm ( according to sign convention )
= .5 x ( 15 + 10 ) / 15 x 10
=
F = 12 cm
