Two small insulating spheres with radius 4.50×10−2 mare separated by a large center-to-center distance of 0.510 m . One sphere is negatively charged, with net charge -2.20 μC , and the other sphere is positively charged, with net charge 3.95 μC . The charge is uniformly distributed within the volume of each sphere.

What is the magnitude E of the electric field midway between the spheres?

Take the permittivity of free space to be ϵ0 = 8.85×10−12 C2/(N⋅m2) .

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as

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
