Dual Nature Of Radiation And Matter

Step 1: Formula for elongation. The elongation in the wire can be calculated using the formula: where: is the applied force, is the length of the wire, is the cross-sectional area of the wire, is Young's modulus.
Step 2: Substituting the values. Thus, the elongation in the wire is .

Step 1: {Define angular momentum}
Angular momentum at maximum height is given by: where is the maximum height.
Step 2: {Find the horizontal velocity}
The horizontal component of velocity remains constant:
Step 3: {Find the maximum height}
Using the kinematic equation: Substituting :
Step 4: {Calculate angular momentum}
Thus, the correct answer is (A) .
