Question

The two-dimensional motion of a particle, described by r = ( i ^ + 2 j ^ ​ ) A cos ω t is a/an: A. parabolic path B. elliptical path C. periodic motion D. simple harmonic motion Choose the correct answer from the options given below:NEET 2024 (Re-NEET)

TestHub · Accepted Answer

r = ( i ^ + 2 j ^ ​ ) A cos ω t x = A cos ω t y = 2 A cos ω t y = 2 x The path is straight line. The motion is SHM and periodic as d t d r ​ = − ( i ^ + 2 j ^ ​ ) ω A sin ω t d t 2 d 2 r ​ = − ( i ^ + 2 j ^ ​ ) ω 2 A cos ω t a = − ω 2 r
