Answer:

(A). The magnetic field is zero at 0.8 cm.

(B). The magnetic field is zero at 5.56 cm.

Explanation:

Given that,

Current in first wire I = 6.0 A

Current in second wire = 2.6 A

Distance x_{1}=-2.2 cm

Distance x_{2}=+2.2\ cm

(A). We need to calculate the magnetic field

If the currents are in the same direction

The magnetic field is in both wires

B_{1}=B_{2}

\dfrac{\mu_{0}I_{1}}{2\pi(r)}=\dfrac{\mu_{0}I_{2}}{2\pi(x-r)}

Put the value into the formula

\dfrac{I_{1}}{(r)}=\dfrac{I_{2}}{4.4-r}

Put the value into the formula

\dfrac{6.0}{r}=\dfrac{2.6}{4.4-r}

x = \dfrac{6.0\times4.4}{8.6}

x =3.0\ cm

The point where the magnetic field is zero

x = 3.0-2.2 = 0.8\ cm

The magnetic field is zero at 0.8 cm.

(B). We need to calculate the point where the magnetic field zero

If the currents are in the opposite direction

The magnetic field is in both wires

B_{1}=B_{2}

\dfrac{\mu_{0}I_{1}}{2\pi(r)}=\dfrac{\mu_{0}I_{2}}{2\pi(x+r)}

Put the value into the formula

\dfrac{I_{1}}{(r)}=\dfrac{I_{2}}{4.4+r}

Put the value into the formula

\dfrac{6.0}{r}=\dfrac{2.6}{4.4+r}

x = \dfrac{6.0\times4.4}{3.4}

x =7.76\ cm

The point where the magnetic field is zero

x = 7.76-2.2 = 5.56\ cm

The magnetic field is zero at 5.56 cm.

Hence, This is the required solution.

Two bodies are falling with negligible air resistance, side by side, above a horizontal plane. If one of the bodies is given an
borishaifa [10]

Answer:a

Explanation:

Given

two bodies are falling with negligible air Resistance and one of the body is given a slight horizontal acceleration

since there is no change in vertical acceleration therefore time taken by both bodies is same irrespective of change in horizontal direction

suppose both start from rest from a height of h

time taken

t=\sqrt{\frac{2h}{g}}

The only difference is that body with horizontal acceleration will be some distance away from first

When can a car have no acceleration but still be moving
gregori [183]

Answer:

A. A car can still be moving without acceleration when it has some velocity.

B. A car can come to a stop when moving itself when it has some de acceleration.

C.A ca can start at 0 m/s and speed up to 15 m/s when it has some acceleration.

Explanation:

A. since the car has no acceleration the velocity of the car would help it moving.

B. when the car is moving with some velocity but coming to a stop this is possible of and only if it has some de acceleration

C. since the speed of the car increases from 0 to 15 m/s acceleration is involved. If the speed was constant there would be no acceleration involved.
