Question

• A body of mass 100kg is to be pulled
along a smooth indined plane
whose indination is 3 in 5:
Then the minimum force to be
used along the plane is (g=10m/s^2)​

Answer 1

The force acting on the object due to gravity for sliding down is mgsinθ which is equal to 25 N here.

now, the component of the horizontal force F  

a

​  

 along the incline plane should be equal to 25 N. For that,

F  

a

​  

cos30°=25

F  

a

​  

=

 N

Answer 2

Answer:

☆ Points to note before solving:-

• no friction will act as wedge is smooth
• inclination 3in5 is the ratio of perpendicular/hypotenuse
• Fnet = Fdriving-Fopposing=ma
• in ques like this always draw the free body diagram of the object...

~600 N req to pull the object...

hope its correct..

Good luck
