Force=mass×acceleration In case 1 substituting values 10=M1×2 we get M1 as 5kg And 10 = M2 × 5 we get M2 that equals to 2kg Now both the bodies are tied together so the mass will be sum of both objects that is M1+ M2 = M' and we have to take force as 10N as per question So, 10 = M' × a a= 10/7 = 1.42 m/s²

If a vector can have a magnitude A making an angle ∅ with x axis, then its vertical component is A sin ∅ and horizontal component is A cos ∅. Therefore, in this case, hori. component is 5√3 units and vertical. component is 5 units.

Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.
