Question

An electric field is acting vertically upwards. A small body of mass 1 gm and charge -1uC is projected with a velocity 10 m/s at an angle 45° with horizontal. Its horizontal
range is 2m then the intensity of electric field is (g=10m/s^2)​

Answer 1

Answer:

An electric field is acting vertically upwards on a small body of mass 1gm and charge −1μC is projected with a velocity 10m/s at angle 45

∘

with horizontal. If horizontal range is 2m then intensity of electric field is: (g=10m/s 2)
