Question

Two forces are acting on an object, 8 N to the right and 6 N down. Click on the vector diagram to show the correct net force on the object.

Answer 1

10 N

Step-by-step explanation:

According to the triangle law of addition of two vectors, if the two vectors are represented by the two sides of a triangle, then the resultant of these two vectors is given by the third side of the triangle taken in opposite order.

If there are two vectors A and B inclined at an angle theta, then the resultant is given by

R^2 = A^2 + B ^2 + 2ABCos theta

Here , A = 8 N , B = 6m and theta = 90 degree

So, R^2 = 8^2 + 6^2 + 2 × 8 × 6 × Cos90

R^2 = 100

R = 10 N

Thus, the resultant vector is 100 N.
