Please help find resultant force of the figure

The resultant force will be 5 N in the South West Direction.

Explanation:

Tip:

If we have two vectors A and B, their resultant is:

is the angle between A and B

Since, Force is a vector quantity, the answer to he given diagram will be thought out by Vector Laws of Addition.

Solution:

6N and 9N are in opposite directions, so their resultant will simply be their difference, and it will be pointing in the direction of the vector with larger magnitude.

= 9 - 6

= 3 N

Now, we have two vectors. one of magnitude 4N pointing towards West and the other of magnitude 3N pointing towards South.

They're at an angle of 90°. (=90)Their resultant will lie in between the two vectors, 4N and 3N.(The South West Direction).

It's magnitude will be equal to

(as cos90=0, we're left with the sum of the squares of the two vectors)

= 5N

Therefore, the resultant force will be 5N towards the South-West.

The answer is c hope this

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
