Question

what is the magnitude and direction of Icap + J cap​

Answer 1

Answer:

Magnitude of i cap + j cap equals :

√{(i.i) + (j.j) }=√[1+1]=√2

Or one can also say √{[(coefficient of i cap)^2+[coefficient of j cap]^2}=√2

i is the Magnitude of the vector along x axis direction and j is the Magnitude of the vector along y axis direction.

DIRECTION :

Let the angle made by the resultant with the x axis be β

Tan β = | i|/|j | = 1/1 = 1

β = π/4 = 45°..

Answer 2

Answer:

magnitude of i^+j^=√1+1=√2 and direction is tan-¹(b/a)= tan-¹ 1/1= 45°
