Question

Vector sum of the forces of 5N and 4N can be:(A)10N
(B)4N
(C)3N
(D)5N​

Answer 1

Answer:

B)4N

C)3N

D)5N

Step-by-step explanation:

The Range of the Resultant Force is 1N to 9N.

Minimum is 1N because, when the two force are acting against each other [5N + (-4N) = 1N]

Maximum is 9N because, when the two forces are acting in same direction (5N + 4N = 9N).

Considering the two vector forces acting in any possible direction it will never overshoot the Range.

And since, option b, option c and option d are in the range, they can be considered as the answer to the question.

Answer 2

Concept:

The vector is a quantity having direction.

The sum of vectors means adding the two vectors.

Given:

We are given the two forces 5N and 4N.

Find:

We need to find the vector sum of the forces of 5N and 4N.

Solution:

We know that the vector sum of the two forces A and B lies between the range A-B and A+B.

So we will first calculate A-B:

A-B=5N-4N=N

Now, we will calculate A+B:

A+B=5N+4N=9N

So, Option (B), (C) and (D) are the correct options.

Therefore, we get that vector sum of the forces of 5N and 4N can be option (B), (C) and (D)
