using a scale of 1 centimetre to represent n and find the size and direction of the resultant forces of 30 and 40 and acting at right angle to each other
Answers
Answer:
Sorry bro but i dont know for n but i know for 10
Here in this problem, both forces are at an angle of 90 degrees to each. A parallelogram is made by drawing two remaining sides. The diagonal of the parallelogram will represent the resultant force
Key Points:
Any physical quantity that has a magnitude as well direction is known as vector. It is denoted by an arrow symbol where the length of the arrow represents its magnitude and the head of the arrow represent the direction of the vector.
There are four cardinal directions: north(N), south(S), east(E) and west(W). All these directions are perpendicular to each other and used to represent the direction.
The resultant of two vectors can be determined either by triangle law of vector or parallelogram law of vector. The formula to calculate the magnitude of the resultant is given as:

Answer:
The answer is indeed 50 N and in the end this boils down to being a trigonometry problem and is solved using pythagorean theorem (A²+B²=C²)
The first thing you have to do is transform your values into vectors (Graphic representation of magnitude (Your value in newtons) and direction (The fact you know they are acting perpendicular to one another)
This will give you two arrows (The vectors) that form a triangle of which you can solve the hypotenuse to sum up both other vectors using the pythagorean theorem.
