Teaching Bihar STET Paper 1 (माध्यमिक) Mock Test 2024 Physics Rotational Motion The Angular Momentum
A particle of mass m is moving in yz-plane with a uniform velocity v with its trajectory running parallel to +ve y-axis and intersecting z-axis at z = a (Fig. 7.2). The change in its angular momentum about the origin as it bounces elastically from a wall at y = constant is:
1
mva \({\widehat e_x}\)
2
2mva \({\widehat e_x}\)
3
ymv \({\widehat e_x}\)
4
2ymv \({\widehat e_x}\)
