QNEET-2013-Ph-1530: NEET 2013 Physics - Class 11 NEET-2013-Ph-1530 Solution: The velocity of a projectile at the initial point A is \((2 {i} …

The velocity of a projectile at the initial point A is (2i^+3j^) m/s(2\hat{i} + 3\hat{j})\ \text{m/s}. Its velocity (in m/s) at point B is 2i^−3j^2\hat{i} - 3\hat{j} 2i^+3j^2\hat{i} + 3\hat{j} −2i^−3j^-2\hat{i} - 3\hat{j} −2i^+3j^-2\hat{i} + 3\hat{j}

Multiple Choice Options

  • A 2i^−3j^2\widehat i - 3\widehat j 2 i _ 3 j _
  • B 2i^+3j^2\widehat i + 3\widehat j 2 i + 3 j _
  • C −- _ 2i^−3j^2\widehat i - 3\widehat j 2 i _ 3 j _
  • D −- _ 2i^+3j^2\widehat i + 3\widehat j 2 i + 3 j _

Step-by-Step Verified Solution

At point B X component of velocity remains unchanged while Y component reverses its direction. _ The velocity of the projectile at point B is 2 i ^ _ 3 j ^ m/s.
