A 2-kg object is initially at the bottom of a long 50° inclined plane, and is beginning to slide up this inclined plane. The ini
Over [174]

Answer:

Explanation:

Given

mass of object m=2 kg

inclination \theta =50^{\circ}

\mu _k=0.3

\mu _s=0.4

initial velocity u=3 m/s

acceleration of block during upward motion

a=g\sin \theta -\mu _kg\cos \theta

a=g(\sin 50-0.3\cos 50)

a=5.617 m/s^2

using relation

v^2-u^2=2a\cdot s

where s=distance\ moved

v=final\ velocity

v=0 because block stopped after moving distance s

0-(3)^2=2\cdot (-5.617)\cdot s

s=\frac{4.5}{5.617}

s=0.801

If block stopped after s m then force acting on block is

F=mg\sin \theta =friction force f_r=\mu mg\cos \theta

F>f_r therefore block will slide back down to the bottom

A long, straight, horizontal wire carries a left-to-right current of 20 A. If the wire is placed in a uniform magnetic field of
serg [7]

Answer:

Explanation:

vertical magnetic field B_v = 4 x 10⁻⁵ T.

Magnetic field due to horizontal current at point 20 cm above

= (μ₀/4π ) x (2i / R)

= 10⁻⁷ x 2 x 20/ 20 x 10⁻²

= 2 x 10⁻⁵ T

It will act  coming out of paper. Hence it will be normal to magnetic field given .

So resultant magnetic field

= √ (4² + 2²) x 10⁻⁵ T

= 4.47 X 10⁻⁵ T .
