Question

A charge particle having charge 2 coulomb is thrown

Answer 1

considering the charge travelling in the +ve x axis and electric field in the +ve y axis

so the electric field doesnot effect the x component of the velocity so it travells with the same velocity in the x axis ..

for the force exerted on the body towards y axis

F=qE=2x 10^-6 x 10 = 2 x 10^-5 =ma 

so a = 2 x 10^-5/ 10 x 10-3= 2 x 10^ -3 

 

so y after 10 sec = 1/2 a t ^2 

and similarly u can calculate x after 10 s and get the displacemant and similarly for the velocity
