Explanation Write the expression for momentum of the object as. p = m v (I) Here, p is the momentum of the object, m is the mass of the object and v is the velocity of the object. Write the expression for the impulse acting on the object. I = ∑ F → a v g Δ t (II) Here, I is the impulse acting on the object, F a v g → is average force acting on the object and Δ t is the change in time. Write the impulse - momentum relation. Δ p = I (III) Here, Δ p is the change in momentum. Substitute m v for Δ p and ∑ F → a v g Δ t for I in equation (III)

81 SSM Figure 29-84 shows a cross section of an infinite conducting sheet carrying a current per unit x-length of 2; the current emerges perpendicularly out of the page. (a) Use the Biot-Savart law and symmetry to show that for all points B •P x B P'. Figure 29-84 Problem 81. P above the sheet and all points P' below it, the magnetic field B is parallel to the sheet and directed as shown. (b) Use Ampere's law to prove that B = ½µλ at all points P and P'.
