Question

The vertic componet of a vector is equal to its horizontal component. what is the angle made by the vector with x - axis.​

Answer 1

HEYA MATE HERE U GO.

Let 'theta' be angle made by the vector R with X-axis .

vertical component of R = R sin theta.

Horizontal component of R = R cos theta.

therefore R cos theta = R sin theta = Tan theta = 1 = theta = 45DEGREES

Answer 2

HEYA MATE HERE U GO.

Let A = Ax î + Ay j

horizontal component of a vector = vertical component of a vector

Let theta be the angle made by A with X -axis.

A cos theta = A sin theta

tan theta = 1 = theta = 45degrees.
