Question

Two charged particles of equal charges are placed 1 m apart. The initial acceleration of each of them is
1 ms-2. If their equal mass is 10-gm, find the charge on each of them.

​

Answer 1

Answer:

sqrt.(1/10^11)

force due to one on another

kq^2/r^2

putting values we get

10^9*q^2=10/1000

since net force =mass *accn

by this we get ans

Answer 2

The charge on each of them is 1.05 microcoulomb.

Explanation:

Given that,

Separation between charges, d = 1 m

Acceleration of the charges, $a=1\ m/s^2$

Mass, $m_1=m_1=10\ g=0.01\ kg$

The electric force is balanced by the force due to motion such that,

$\dfrac{kq^2}{d^2}=ma$

$q^2=\dfrac{mad^2}{k}$

$q^2=\dfrac{0.01\times 1\times (1)^2}{9\times 10^9}$

$q=1.05\times 10^{-6}\ C$

or

$q=1.05\ \mu C$

So, the charge on each of them is 1.05 microcoulomb. Hence, this is the required solution.
