Una carga de prueba de 5×10 -4 C recibe una fuerza horizontal hacia la derecha de 3×10-4 N. ¿Cuál es la magnitud de la intensidad del campo eléctrico en el punto donde está colocada la carga de prueba?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
