Four equal +6.00-μc point charges are placed at the corners of a square 2.00 m on each side. (k = 1/4π ε0= 8.99 × 109 n · m2/c2) (a) what is the electric potential (relative to infinity) due to these charges at the center of this square? 153 kv previous answers correct part b (b) what is the magnitude of the electric field due to these charges at the center of the square? n/c

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
