Question

Two forces of 1 N and P N act at a point so that the magnitude of resultant is 1 N and it is perpendicular to
1 N. The value of P in newtons and the angle between the 1 N and P N are​

Answer 1

Answer:

hello dear

Explanation:

Let the 1 N force point in the x direction, thus its vector representation would be 1

i

^

.

The resultant is 1 N and is perpendicular to the initial 1 N force. The vector representation of the resultant is 1

j

^

.

Now let the unit vector along the direction of P N be

x

^

.

Thus we get:

1

i

+P

x

=1

j

or P

x

=1

j

−1

i

The magnitude of this vector

j

−

i

is

2

and if we plot it on the coordinate system we see that it makes an angle of 135

o

with the horizontal.
