Ametal sphere, x, has an initial net charge of −6 × 10−6 coulomb and an identical sphere, y, has an initial net charge of +2 × 10−6 coulomb. the spheres touch each other and then separate. what is the net charge on sphere x after the spheres have separated?

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
