Let the charges be q and-xA0-3qgiven force -0-108N-x21D2-0-108-K-q-3q-1-2-x21D2-0-108-9-xD7-109-xD7-3q2

Two unlike charges separated by a distance of $1 m$ attract each other with a force of $0.108 N$ . If the charges are in the ratio $1 : 3$ , the weak charge is :

$4 μ C$
$2 μ C$
$6 μ C$
$5 μ C$

Let the charges be $q$ and $3 q$
given force $= 0.108 N$
$\Rightarrow 0.108 = \frac{K (q) (3 q)}{(1)^{2}}$
$\Rightarrow 0.108 = 9 \times 10^{9} \times 3 q^{2}$

Two unlike charges separated by a distance of 1m attract each other with a force of 0.108N. If the charges are in the ratio 1:3, the weak charge is :4μC2μC6μC5μC

Let the charges be q and 3qgiven force =0.108N⇒0.108=K(q)(3q)(1)2⇒0.108=9×109×3q2

Two unlike charges separated by a distance of $1 m$ attract each other with a force of $0.108 N$ . If the charges are in the ratio $1 : 3$ , the weak charge is :

$4 μ C$
$2 μ C$
$6 μ C$
$5 μ C$

Let the charges be $q$ and $3 q$
given force $= 0.108 N$
$\Rightarrow 0.108 = \frac{K (q) (3 q)}{(1)^{2}}$
$\Rightarrow 0.108 = 9 \times 10^{9} \times 3 q^{2}$
