Increase object mass or decrease the distance in between objects. Of the two, force is proportional to mass - double the mass, double the force. Distance is to the square - reduce distance to half, force will increase by 4x.

<span>Reducing the distance between them. In theory, also increasing the mass; but you can't really change the mass of an object. However, you can compare the forces if you replace an object by a different object, which has a different mass.

i hope this will work..

What must be the distance (in meters) between a point charge q1 = 16 μC and a point charge q2 = 32 μC for the electrostatic forc

adoni [48]

Answer:

d = 0.71 meters

Explanation:

It is given that,

Charge 1, $q_1=16\ \mu C=16\times 10^{-6}\ C$

Charge 2, $q_2=32\ \mu C=32\times 10^{-6}\ C$

Electrostatic force between charges, F = 9 N

Let d is the distance between the charges. The electrostatic force between the charges is given by the product of charges and divided by square of distance between them. Mathematically, it is given by :

$F=k\dfrac{q_1q_2}{d^2}$

$d=\sqrt{\dfrac{kq_1q_2}{F}}$

$d=\sqrt{\dfrac{9\times 10^9\times 16\times 10^{-6}\times 32\times 10^{-6}}{9}}$

d = 0.71 meters

So, the distance between the charges is 0.71 meters. Hence, this is the required solution.

Ugo [173]

Answer:

Current, I = 1.08 A

Explanation:

Given that,

Length of the copper wire, l = 12 cm = 0.12 m

Mass of the wire, m = 16 g = 0.016 kg

Magnetic field, B = 1.2 T
