1.
m = mass of Mr. Ure = 65 kg
g = acceleration due to gravity = 9.8 m/s²
force of earth's gravity on Mr. Ure is given as
F = mg
F = 65 x 9.8
F = 637 N
2.
F = force of gravity on car = 3050 N
m = mass of the car = ?
g = acceleration due to gravity = 9.8 m/s²
force of gravity on car is given as
F = mg
3050 = m (9.8)
m = 3050/9.8
m = 311.22 kg
3.
m = mass of Mr. Rees = 90 kg
g = acceleration due to gravity = 9.8 m/s²
force of earth's gravity on Mr. Rees is given as
F = mg
F = 90 x 9.8
F = 882 N
Answer:
Value of electric field along the axis and equitorial axis
and
respectively.
Explanation:
Given :
Distance between charges , ![d = 3 \ mm =\dfrac{3}{1000}\ m=3\times 10^{-3}\ m.](https://tex.z-dn.net/?f=d%20%3D%203%20%5C%20mm%20%3D%5Cdfrac%7B3%7D%7B1000%7D%5C%20m%3D3%5Ctimes%2010%5E%7B-3%7D%5C%20m.)
Magnitude of charges , ![q=1\ nC = 10^{-9}\ C.](https://tex.z-dn.net/?f=q%3D1%5C%20nC%20%3D%2010%5E%7B-9%7D%5C%20C.)
Dipole moment , ![p=qL=10^{-9}\times 3\times 10^{-3}=3\times 10^{-12} \ C\ m.](https://tex.z-dn.net/?f=p%3DqL%3D10%5E%7B-9%7D%5Ctimes%203%5Ctimes%2010%5E%7B-3%7D%3D3%5Ctimes%2010%5E%7B-12%7D%20%5C%20C%5C%20m.)
Case A) (x,y) = (12.0 cm, 0 cm) :
Electric field of dipole in its axis ,
![E=\dfrac{2kp}{r^3}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B2kp%7D%7Br%5E3%7D)
Putting all values and ![r=12\times 10^{-2}\ m.](https://tex.z-dn.net/?f=r%3D12%5Ctimes%2010%5E%7B-2%7D%5C%20m.)
We get , ![E=31.25\ N/c.](https://tex.z-dn.net/?f=E%3D31.25%5C%20N%2Fc.)
Case B) (x,y) = (0 cm, 12.0 cm) :
Electric field of dipole on equitorial axis ,
![E = \dfrac{kp}{r^3}](https://tex.z-dn.net/?f=E%20%3D%20%5Cdfrac%7Bkp%7D%7Br%5E3%7D)
Putting all values and
We get , ![E = 15.625\ N/c.](https://tex.z-dn.net/?f=E%20%3D%2015.625%5C%20N%2Fc.)
Hence , this is the required solution.
