- What will be the field strength from a 1.25* 10^-3 when measured 0.4m from the charge?

Explanation:

I'm assuming your charge is in Coulombs so I will proceed that way. The formula for this electric field problem is

where k = 9.0 × 10⁹. Filling in:

gives us an electric field value of

7.0 × 10⁷ N/C

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
