Electric field lines generally show the properties to account for nature of electric fields. Some general properties of these lines are as follows:
- Electric field lines start from a positive charge and end at a negative charge, in case of a single charge, electric field lines end at infinity
- In a charge-free region, electric field lines are continuous and smooth
- Two electric field lines never intersect or cross each other, as if they do, there will be two vectors depicting two directions of the same electric field, which is not possible
- These lines never form a closed loop. This is because an electric field is conservative in nature and hence the lines don’t form a closed loop.

{tex}\vec a = 2\hat i + 4\hat j - 5\hat k{/tex}
{tex}\vec b = \lambda \hat i + 2\hat j + 3\hat k{/tex}
{tex}\vec a + \vec b = \left( {2 + \lambda } \right)\hat i + 6\hat j - 2\hat k{/tex}
Unit vector along
{tex}\vec a + \vec b = \frac{{\vec a + \vec b}}{{\left| {\vec a + \vec b} \right|}}{/tex}
{tex}= \frac{{\left( {2 + \lambda } \right)\hat i + 6\hat j - 2\hat k}}{{\sqrt {{{\left( {2 + \lambda } \right)}^2} + {{\left( 6 \right)}^2} + {{\left( { - 2} \right)}^2}} }}{/tex}
{tex}= \frac{{\left( {2 + \lambda } \right)\hat i + 6\hat j - 2\hat k}}{{\sqrt {{{\left( {2 + \lambda } \right)}^2} + 40} }}{/tex}
ATQ , {tex}\vec c.\left( {\vec a + \vec b} \right) = 1{/tex}
{tex}\left( {\hat i + \hat j + \hat k} \right).\left( {\frac{{\left( {2 + \lambda } \right)\hat i + 6\hat j - 2\hat k}}{{{{\left( {2 + \lambda } \right)}^2} + 40}}} \right) = 1{/tex}
{tex}\frac{{\left( {2 + \lambda } \right) + 6 - 2}}{{\sqrt {{{\left( {2 + \lambda } \right)}^2} + 40} }} = 1{/tex}
{tex}2 + \lambda + 4 = \sqrt {{{\left( {2 + \lambda } \right)}^2} + 40} {/tex}
Sq both sides,
{tex}{\lambda ^2} + 36 + 12\lambda = {\left( {2 + \lambda } \right)^2} + 40{/tex}
{tex}\lambda = 1{/tex}

| 1. Meaning | It is the ratio in which old partners agree to sacrifice their share of profit in favour of new partners/partner | It is the ratio in which continuing partner acquires the share of profit from outgoing partner/partner |
| 2. Effect | It reduces the profit share of the existing partners. | It increases the profit share of the remaining partners. |
| 3. Objective | It is calculated to ascertain the share of profit and loss given up by the existing partners in favour of new partners/partner. | It is calculated to ascertain the share of profit and loss acquired by the remaining partners (of the new firm in case of retirement) from the retiring or deceased partner. |
| 4. Time | It is calculated at the time of admission of new partners/partner. | It is calculated at the time of retirement/death of old partners/partner. |
| 5. Calculation | Sacrificing Ratio = Old Ratio – New Ratio | Gaining Ratio = New Ratio – Old Ratio |

Formula for calculating drift velocity of electron in a conductor of constant cross-sectional area is given by
V = 1/ nAq
Where, ‘v’ is the drift velocity of the electrons
‘I’ is the current flowing through the conductor (amperes)
‘A’ is the cross-section area of the conductor (m2)
‘q’ is the charge on the charge carrier (coulombs, c)
