Part B
D
Part C

13 N

Explanation:

From the question,

If two forces act at right angle to each other, Their result force can be calculated using Pythagoras theorem.

R'² = R₁²+R₂²....................... Equation 1

Where R' = Resultant force, R₁ = First force, R₂ = Second force.

Given: R₁ = 12 N, R₂ = 5 N

Substitute these values into equation 1

R'² = 12²+5²

R'² = 144+25

R'² = 169

R' =

R' = 13 N.

Hence the resultant force is 13 N
