Physics · MOTION IN A PLANE
हिन्दीGiven below are two statements: Statement I: In projectile motion, the horizontal component of velocity remains constant throughout the motion in the absence of air resistance. Statement II: In uniform circular motion, the centripetal acceleration vector remains constant in both magnitude and direction. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
Explanation
Statement I is correct because horizontal acceleration is zero (\( a_x = 0 \)). Statement II is incorrect because although magnitude \( a_c = v^2/R \) is constant, its direction continuously changes towards the center.
