Correct option is B
When the uncertainty in position (Δx) is equal to the uncertainty in momentum (Δp), the uncertainty in velocity (Δv) becomes:
(b) 1/2m√(h/π)
When the uncertainty in position (Δx) is equal to the uncertainty in momentum (Δp), the uncertainty in velocity (Δv) becomes:
(b) 1/2m√(h/π)
Consider the interaction forces between two protons separated by a distance of the order of 1 femtometer ($10^{-15}m$). The correct order of the strengths of the electromagnetic, gravitational and nuclear forces acting between them is
A particle is found to be at rest when observed from a reference frame S1 and the same particle is found to move with a constant velocity when observed from another frame S2. Which of the following statements is true?
Which of the following statements about average velocity is NOT correct?
If the acceleration of a body is halved and mass remains constant, the force will
A ball is dropped from rest. What will be the velocity of the ball after falling 20 m? (Take g = 10 m/s²)
