Question

How to find the normal reaction of an object being puled at 45 degree

Answer 1

Explanation:

F = ma ----> vector

N = ma (if the object is pushed from rest )

so, Im.aI = ImI . IaI cos∅

= m.a cos(45)

N = ma/√2

Answer 2

Answer and Explanation:

To find normal reaction of an object being pulled at 45° can be found out by resolving the force vector

Resolving or resolution of vectors is the splitting of vectors into its components in the X-axis and Y-axis

For this particular question,

first we draw FBD or Free Body Diagram of the object

From the FBD we get,

N + Fsin45 = mg

N = mg - Fsin45

Therefore,

Normal reaction on the object = mg - Fsin45
