Weight mg of a block is a force acting downward toward centre of the earth. A block of mass `1 kg` is placed on an inclined plane as shown in figure. Find the x-component and y-component of weight of the block are

Options

A. `6 N, -8 N`
B. `6 N, 8 N`
C. `8 N, 6 N`
D. `8 N, -6 N`

Answer

A

Explanation

`mg = 1xx10= 10N`
From figure, the x-component is
`mg sin 37^(@) = 1xx10xx3/5= 6N`
and y-component is
`-mg cos 37^(@)= -1xx10xx4/5= -8 N`
