Velocity of Ram = 6i
Velocity of Shyam = 6Sin30i + 6Cos30j

Relative velocity = 6i - 6Sin30i - 6Cos30j
= 6i - 3i - 3√3j
= 3i - 3√3j

Magnitude of relative velocity = sqrt(3^2 + (3√3)^2)
= 6 m/s

Shyam moves 30⁰east of North so the angle between them is 60⁰,then

Vrs=√Vr^2+Vs^2-2 (Vr)(Vs)COS60

=√6^2+6^2-2(6)(6)(1/2)

=√36+36-36

=√36

=6m/s
