Question

The angle between P and the resultant of 3. (++),(P-O) is 1) Zero 2) Tan-'(P/Q) 4) Tan-1 P-Q P+Q 3) Tan-Q/P)
​

Answer 1

Answer:

Step 1: Resultant Calculation

Let the resultant be

R

∴

R

=(

P

+

Q

)+(

P

−

Q

)

⇒

R

=2

P

....(1)

Step 2: Angle between

R

and

P

From (1) we can say that,

R

is in same direction along

P

with twice its magnitude. Thus,

R

and

P

are parallel.

Therefore, the angle between

R

and

P

is zero.
