Answer:
56.82 Kg
Explanation:
Given data:
1 Kg = 2.20 lbs
Number of kilogram in 125 lbs = ?
Solution:
lbs is used for pound. lb is abbreviation of libra. It is Latin word meaning balance.
Both kilogram and pounds are units of mass. Pound is smaller unit than kilogram.
one Kg = 2.20 lbs
Number of kg in 125 lbs:
125 lbs × 1 Kg/2.20 lbs
125 lbs.Kg/2.20 lbs
56.82 Kg
D as it only has a negative effect when being used and it is small at that anyway.
Answer: E = 2.455 x 10^5 N/C
Explanation:
q1 = 1.2x10^-7C
q2 = 6.2x10^-8C
Electric field, E = kQ/r²
where k = 9.0x10^9
since the location is (27 - 5)cm from q1
hence electric field, E1 = k*q1/r²
E1= (9x10^9 x 1.2x10^-7)/(0.22)² = 22314.05 N/C
for q2:
E1 = k*q2/r²
E2 at 5cm
E2 = (9x10^9 x 6.2x10^-8)/(0.05)² = 223200 N/C
Hence, the total electric field at 5cm position is
E = E1 + E2
E = 22314.05 + 223200 = 245514.05 N/C
E = 2.455 x 10^5 N/C
