Question

The magnitude of contact force is given by...
A) R=√N+√f
B) R= N²+f²
C) R²= N²+f²
D) R= N+f​

Answer 1

Answer:

C.

R^2= N^2+ f^2

hope it's correct..

Answer 2

Answer:

Option C) is the answer.

Explanation:

Understand it simply in the vector form.

We know forceis a vector and resultant force is the sum of N vector and F vector.

So,

Magnitude R =( (N+F)^2) ^1/2.

R^2 = N^2 + F^2 + 2NFcos¤

(The angle is not given so assume it be 90)

Hence option c)..

Hope it helps..
