Caculate the electric field due to a dipole on its axial line and equatorial line

Answer»

ELECTRIC field due to dipole is given by,

but EA=1/4πEo q/(r+h) 2AND Eb=1/4πEo q/(r-h) 2

as Eb>Ea and act in opposite direction so

E=1/4πEo q/(r-h) 2 - 1/4πEo q/(r+h) 2=1/4πEo q(4rh)/(r2-h2) 2

but q×2h=p,the dipole moment

E =1/4πEo 2pr/(r2-a2)2 (along px)

Answer» Required answer :- DISTANCE travelled by the body in 10 seconds is 2 m EXPLANATION :- As per the given information we have, MASS of the body is (m) 0.5 kg The body is resting of FRICTIONLESS surface [u =0] FORCE acting is 2000 dynes Time TAKEN is 10 s We have to find the distance travelled From equations of motion, We know that , $\implies \: s = ut + \dfrac{1}{2} at {}^{2}$ where, s = distance covered u = initial velocity t = time taken a = acceleration So, we can apply this formula But we don't know the acceleration of the body . So,Lets calculate acceleration of body. We know that, $\implies \: f = ma$ F = force m = mass a = acceleration F = 2000 dynes Converting dynes - Newtons $\implies{F = 2000\times 10^{-5} N }$ $\implies{F = 2 \times 10^3× 10^{-5} N}$ $\implies{F = 2× 10^{-2}N}$ F = m × a $\implies 2 \times 10 {}^{ - 2} = 0.5 \times a$ $\implies \dfrac{2}{100} = \dfrac{5}{10} \times a$ $\implies \dfrac{2}{10} = 5a$ $\implies \dfrac{1}{5} = 5a$ $\implies 25a = 1$ $\implies a = \dfrac{1}{25} \: m/s {}^{2}$ Substituting these values in formula $\implies \: s = ut + \dfrac{1}{2} at {}^{2}$ $\implies \: s = 0(10) + \dfrac{1}{2} \times \dfrac{1}{25} \times (10) {}^{2}$ $\implies \: s = \dfrac{1}{50} \times 100$ $\implies \: s = 2m$ So, distance travelled in 10 seconds by the body is 2m

A body of mass 0.5 kg is resting on a frictionless surface.When a force of 2000 dyne acts on it for 10 s, then calculate the distance traveled by it in 10 seconds.

Answer»

Required answer :-

DISTANCE travelled by the body in 10 seconds is 2 m

EXPLANATION :-

As per the given information we have,

MASS of the body is (m) 0.5 kg
The body is resting of FRICTIONLESS surface [u =0]
FORCE acting is 2000 dynes
Time TAKEN is 10 s

We have to find the distance travelled

From equations of motion,

We know that ,

$\implies \: s = ut + \dfrac{1}{2} at {}^{2}$

where,

s = distance covered
u = initial velocity
t = time taken
a = acceleration

So, we can apply this formula But we don't know the acceleration of the body . So,Lets calculate acceleration of body.

We know that,

$\implies \: f = ma$

F = force
m = mass
a = acceleration

F = 2000 dynes

Converting dynes - Newtons

$\implies{F = 2000\times 10^{-5} N }$

$\implies{F = 2 \times 10^3× 10^{-5} N}$

$\implies{F = 2× 10^{-2}N}$

F = m × a

$\implies 2 \times 10 {}^{ - 2} = 0.5 \times a$

$\implies \dfrac{2}{100} = \dfrac{5}{10} \times a$

$\implies \dfrac{2}{10} = 5a$

$\implies \dfrac{1}{5} = 5a$

$\implies 25a = 1$

$\implies a = \dfrac{1}{25} \: m/s {}^{2}$

Substituting these values in formula

$\implies \: s = ut + \dfrac{1}{2} at {}^{2}$

$\implies \: s = 0(10) + \dfrac{1}{2} \times \dfrac{1}{25} \times (10) {}^{2}$

$\implies \: s = \dfrac{1}{50} \times 100$

$\implies \: s = 2m$

So, distance travelled in 10 seconds by the body is 2m

Answer»

WOOD is a cuboid

Length=L=4cm
Breadth=5cm
Height=H=20cm

We KNOW

$\boxed{\sf Volume=LBH}$

$\\ \sf\longmapsto Volume=4\times 5\times 20$

$\\ \sf\longmapsto Volume=20\times 20$

$\\ \sf\longmapsto Volume=400cm^3$
