Question

A force of F=10kg wt is exerted horizontally against a 60kg block which in turn pushes a 40kb block.if the blocks are on a friction less surface,what force does one block exert on the second g=10m/s

Answer 1

Net Force = Applied Force - Frictional ForceNet Force = Applied Force - Frictional Force

⟹Fnet=100−f⟹Fnet=100−f

Where,Where,

f = Frictional Forcef = Frictional Force

a = Acceleration = Force/Mass a = Acceleration = Force/Mass 

Applied Force = 100 NApplied Force = 100 N

⟹a=2−f/50⟹a=2−f/50

Since velocity is constant that means the acceleration of the body is 0.

⟹0=2−f/50⟹0=2−f/50

⟹f=100N
HOPE THIS WAS HELPFUL

Answer 2

Hey !

______________________________

Two blocks are in contact on a frictionless table. A horizontal force is applied to one block, as shown in the figure below.
