Answer:
Mass of the object, [tex]m=1.58\times 10^{-3}\ kg[/tex]
Explanation:
It is given that,
Charge on an object, [tex]q=25\ \mu C=25\times 10^{-6}\ C[/tex]
Electric field, E = 620 N/C
We need to find the mass of this object. Let m is the mass of the object. It can be calculated as :
[tex]ma=qE[/tex]
[tex]m=\dfrac{qE}{a}[/tex], here a = g (as it is vertically downward)
[tex]m=\dfrac{25\times 10^{-6}\times 620}{9.8}[/tex]
m = 0.00158 kg
[tex]m=1.58\times 10^{-3}\ kg[/tex]
So, the mass of the object is [tex]1.58\times 10^{-3}\ kg[/tex]. Hence, this is the required solution.
