••13 In Fig. 29-44, point P₁ is at distance R = 13.1 cm
on the perpendicular bisector of a straight wire of length
L = 18.0 cm carrying current i = 58.2 mA. (Note that the
wire is not long.) What is the magnitude of the magnetic
field at P₁ due to i?

If the statement is false, correct the statement to make it true. 12. An object in uniform circular motion has a constant velocity while experiencing centripetal acceleration. 13. An object travelling in uniform circular motion experiences an outward centrifugal force that tends to pull the object out of the circular path. 14. An object with less inertia can resist changes in motion more than an object with more inertia. 15. For an object sliding on a horizontal surface with a horizontal applied force, the frictional force will always increase as the applied force increases.arrow_forwardPls help asaparrow_forward
