14) A vary long wire carries a uniform linear charge density. You measure the potential difference between a point 0.025 m from the wire and 0.01 m from the wire to be 575 V. What is the linear charge density on the wire? 15) Two large, parallel, conducting plates carry opposite charges of equal magnitude, are separated by 45 mm, and have a potential difference between them of 360 V. (a) What is the magnitude of the electric field between the plates? (b) What is the magnitude of the force the electric field exerts on a particle with charge 2.4 nC if it is placed between the plates?

Hello, i really need help on this two problems of Physic II, but because I am a bit slow so can anyone help with a step-by-step answer? Thank you 

14) A vary long wire carries a uniform linear charge density. You measure the potential
difference between a point 0.025 m from the wire and 0.01 m from the wire to be 575 V.
What is the linear charge density on the wire?
15) Two large, parallel, conducting plates carry opposite charges of equal magnitude, are
separated by 45 mm, and have a potential difference between them of 360 V.
(a) What is the magnitude of the electric field between the plates?
(b)
What is the magnitude of the force the electric field exerts on a particle with charge
2.4 nC if it is placed between the plates?
