A -4.4 nC charge exerts a repulsive force of 36 mN on a second charge which is located a distance of 0.70 m away from it. What is the charge (magnitude and sign) of the second charge?

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

this would be about 43%

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
