One object has a charge of +5.0 · 10-6 c, and a second object has a charge of +2.0 · 10-6

ruslelena [56]

The electrostatic force between two charged objects is given by
$F=k \frac{q_1 q_2}{r^2}$
where
k is the Coulomb's constant
q1 is the charge of the first object
q2 is the charge of the second object
r is the separation between the two objects

In our problem:
$q_1=+5.0 \cdot 10^{-6} C$
$q_2 = +2.0 \cdot 10^{-6} C$
$r=0.5 m$
So if we plug these numbers into the equation, we can find the electrostatic force between the two objects:
$F=(8.99 \cdot 10^9 Nm^2C^{-2}) \frac{(5.0 \cdot 10^{-6} C)(2.0 \cdot 10^{-6}C)}{(0.5 m)^2}=0.36 N$

At which location would an objects weight be the greatest. 1.pluto 2.earth 3.sun 4.moon

Maslowich

Weight of the object is given as

$Weight = mg$

so weight of the object will be maximum where gravity(g) will be maximum

so here out of all given four the gravity "g" will be maximum at the surface of SUN as we know that sun will be of maximum mass out of all four planets

as we know that

$g = \frac{GM}{R^2}$
