Normal reaction N is a force exerted by ...

Normal reaction `N` is a force exerted by the surface on the block perpendicular to the surface to contact. A block of mass `1 kg` is placed on inclined plane of inclintation `37^(@)` as shown in the figure
Find the component of normal reaction `N= 8 N` on the block x-axis and y-axis

A

`-4.8 N, 6.4 N`

B

`6.4 N, 4.8 N`

C

`10 N, 0`

D

`4.8 N, 6.4 N`

Text Solution

Verified by Experts

The correct Answer is:
A

The x-component of normal reaction `N` is

`-N cos 53^(@)= -8xx3/5= -4.8 N`
The y-component of normal reaction `N` is `N sin 50^(@)` ltbr `= 8xx4/5= (32)/5= 6.4N`
