Ballooning is a process by which some spiders travel through the air by releasing long strands of silk that catch a breeze. Under certain conditions, electric forces can provide much or even all of the upward force during liftoff. The earth has an electric field that averages 120 N/C pointing downward. Silk acquires a negative charge as it emerges from the spider's spinneret. (The spider's body stays neutral by discharging any positive charge to its surroundings.) Suppose a 0.20 mg spider deploys a long strand of silk with a total charge of -25 NC. Part A If the spider lets go of a leaf, what is its initial upward acceleration while its speed is slow enough for drag to be neglected?
