Properties Of Charge Flashcards
1
Q
First property??
A
Quantisation of Charge
a body can have charge of e or multiples of e
Q = ne
2
Q
Second property???
A
Coulomb’s Law
Electrostatic force F = Kq1q2/ Dr²
*q1 and q2 are magnitude of charges
Like charges - repulsive force
Unlike charges - attractive force
3
Q
Third property???
A
Potential energy of Charge particle is given by E = Kq1q2/ r
q1 & q2 are sign + magnitude
PE - positive then repulsive force
- negative then attractive force
4
Q
Fourth property???
A
When a charge particle q is accelerated by potential difference of V volt…..KE = qv
q - charge…v- potential difference
5
Q
Unit of energy of charges particle
A
eV (electron volt)
1eV = 1.6 × 10-19 J
