Two simple harmonic motions with the same frequency act on a particle at right angles ie, along X and Y-axis. If the two amplitudes are equal and the phase difference is , the resultant motion will be:
A circle
An ellipse with the major axis along y-axis
An ellipse with the major axis along x-axis
A straight line inclined at 45o to the x-axis
A particle moving along the X-axis executes simple harmonic motion; then the force acting on it is given by:
-AKx
A cos Kx
A exp(-Kx)
