Where:
is the speed of sound
is half the time the sound wave travels since the person speaks, the sound wave hits the hill and then returns to the person again as an echo
is the distance between the person and the hill
So, we have to find :
Finally:
Answer:
E= 2.158× 10*5N/C
Explanation:
K= 8.99×10*9, q= 6×10*-6C, d= 0.5m
E= kq/d*2
E= (8.99×10*9× 6×10*-6)/0.5*2
E= 215760
E= 2.158 ×10*5N/C
