Potential energy = (mass) x (gravity) x (height)
Divide each side by (G x H) : Mass = PE / (G x H)
PE = 6 joules
Gravity = 9.8 m/s
Height = 3 m
Mass = 6 / (9.8 x 3) =
6 / (29.4) = <em>0.204 kg</em>
(weighs about 2 newtons or 7.2 ounces on Earth)

- <em>Distance</em><em> </em><em>=</em><em> </em><em>3</em><em>2</em><em> </em><em>m</em>

Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity
Electric field E = 700 N/C
Electric force will be equal to , here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
So charge will be equal to
