Answer:

Force of friction is 10 N.

Explanation:

Given:

Mass of the table is, m=4\textrm{ kg}

Force acting towards right, F=50\textrm{ N}

Net acceleration of the table, a=10\textrm{ }m/s^{2}

Let the force of friction acting on the table to the left be f N.

Therefore, net force acting on the table is given as,

F_{net}=F-f=50-f

Now, as per Newton's second law of motion,

F_{net}=ma

Equating the above two equations, we get

50-f=ma\\f=50-ma\\f=50-(4\times 10)\\f=50-40=10\textrm{ N}

Therefore, the magnitude of the force of friction acting on the table is 10 N to the left direction.

ANEK [815]

A proton travels through a constant magnetic field in the negative y-direction while moving in the negative x-direction. The proton will be subject to a magnetic pull that is directed into the page. Option B is correct.

<h3>What is the right-hand thumb rule?</h3>

Hold a current-carrying conductor in your right hand with your thumb pointing in the direction of the current then wrap your fingers around the conductor and orient them in the direction of the magnetic field lines.

A proton travels through a constant magnetic field in the negative y-direction while moving in the negative x-direction.

The proton will be subject to a magnetic pull that is directed into the page.

Hence, option B is correct.
