Question

When two right angled vectors of magnitude 2 units and √5 units combine,
what is the magnitude of their resultant?​

Answer 1

Answer:

Resultant is 3 unit

Explanation:

R^2=A^2 + B^2

here R is resultant

A= 2 unit

B= √5 unit

R^2= (2)^2 + (√5) ^2

= 4. + 5

= 9

R= 3 unit

Answer 2

Answer:

resultant is 3 unit

Explanation:

R^2=A^2+B^2

Here R is resultant

A=2 unit

B=√5 unit

R^2=(2)^2+(√5)^2

=4•+5

=9

R=3 unit
