Above the ground, a 1 m long wire is suspended horizontally perpendicular to a line running from its center to a nearby observer

Anit [1.1K]

Answer:

a) 0.09N b) positive x direction

Explanation:

Force on a conductor carrying current in a magnetic field can be expressed as;

F = BILsin(theta) where

F is the force on the conductor (wire)

B is the uniform magnetic field I'm Tesla = 1.8Tesla

I is the current in the wire = 5×10^-2A

L is the length of the wire = 1m

theta is the angle that the conductor make with the magnetic field = 90° (since the wire in the horizontal direction is perpendicular to the field acting upwards)

Substituting this value in the formula to get F we have;

F = 1.8×5×10^-2×1 × sin90°

F = 0.09N

The force on the wire is 0.09N

b) The direction of the force is in the positive x direction since the wire acts horizontally to the magnetic field.

A small glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of 39.0 ∘ abov

zvonat [6]

Answer:

kinetic energy of glider = -0.376 j

Explanation:

Original distance by which the spring is compressed can be determine by using law of conservation of energy (As spring slide from glider, it gain some potential energy. On the top of track there is glider’s potential energy exist)

$\frac{1}{2} kx^2 = mgh$
