Answer:
R=19 N
Explanation:
Given that forces are taking opposite to each other.
Take
F₁ = 86 N ( Towards right ,take positive)
F₂ = - 67 N ( Towards left)
Given that the angle between above two forces is 180° so the resultant can be given as
Lets take the resultant = R N
R= F₁ + F₂
Now by putting the values
R= 86 N - 67 N
R=19 N
Therefore the resultant force on the block box will be 19 N.
