Resolve the vector A = A(x) hati + A(y)h...

Resolve the vector `A = A_(x) hati + A_(y)hatj` along an perpendicular to the line which make angle `60^@` with x-axis.

Text Solution

Verified by Experts


So the component along line `= |A_(y) cos 30^(@) + A_(x) cos 60^@|`
and perpendicular to line = `= |A_(x) sin 60^(@) + A_(y) sin 30^@|`.
