Along straight metal rod has a radius of 5.00 cm anda charge per unit length of 30.0 nc/m. find the electric field (a)3.00 cm, (b) 10.0 cm, (c) 100cm from the axis of the rod, wheredistances are measured perpendicular to the rod.

given,

radius of rod = 5 cm

charge per unit length (λ) = 30.0 n C/m = 30 × 10⁻⁹ C/m

electric field duel to long straight wire =

a) distance = 3 + 5 = 8 cm

= 18 × 10⁹

E = 6750 N/C

b) distance = 10 + 5 = 15 cm

= 18 × 10⁹

E = 3600 N/C

c) distance = 100 + 5 = 105 cm

= 18 × 10⁹

E =514.28 N/C

explanation:

because they are cartillidge

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )
