a. " for every action there is an equal and opposite reaction".

b. The electric fan does not stop moving just after the switch turns off because of rational inertia force.

c. The force applied to first vehicle is 120N.

d. In my view it doesn't support the law of conservation of momentum. Momentum of 1 and 2 object before the collision is equal to the total momentum of two object after collision.

Find electric field at point p which is a distance l away from the both +q and -q

denis-greek [22]

Answer:

$\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{I^{2} }+\frac{1}{4\times(pie)\times\text{E}} \times\frac{-q}{I^{2} }$

Explanation:

As given point p is equidistant from both the charges

It must be in the middle of both the charges

Assuming all 3 points lie on the same line

Electric Field due a charge q at a point ,distance r away

$=\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{r^{2} }$

Where

q is the charge
r is the distance
$E$ is the permittivity of medium

Let electric field due to charge q be F1 and -q be F2

I is the distance of P from q and also from charge -q

⇒

F1 $=\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{I^{2} }$

F2 $=\frac{1}{4\times(pie)\times\text{E}} \times\frac{-q}{I^{2} }$

⇒

F1+F2= $\frac{1}{4\times(pie)\times\text{E}} \times\frac{q}{I^{2} }+\frac{1}{4\times(pie)\times\text{E}} \times\frac{-q}{I^{2} }$

Two parallel wires separated by 3.55 cm repel each other with a force per unit length of 1.70 10-4 N/m. The current in one wire

Pepsi [2]

Explanation:

Given that,

Distance between two parallel wires, d = 3.55 cm

Force per unit length, $F/L=1.7\times 10^{-4}\ N/m$

Current in one wire, I = 4.8 A

(a) The force acting per unit length in the wire is given by :

$\dfrac{F}{L}=\dfrac{\mu_oI_1I_2}{2\pi d}$

Substituting all the values in above formula to find I₂ as:

$1.7\times 10^{-4}=\dfrac{4\pi \times 10^{-7}\times 4.8I_2}{2\pi \times 3.55\times 10^{-2}}$

$I_2=6.28\ A$

(b) Since, it is given that the two conductors repel each other, it means that the current is flowing in opposite direction.

(c) If the direction of current is reversed, they will start attracting towards each other and it the one current is doubled, the force per unit length will gets doubled.
