Can someone solve this problem?

(14%) Problem 4: A uniformly charged rod with total charge Q = 6.29 AC is located on the y axis with its lower and upper endpoints placed a = 1.57 m and b = 5.23 m above the origin, respectively. Note that y-axis the point labeled P is placed at the origin. See the figure. y = b- + + + ++++++ O y = a- X-axis Otheexpertta.com 25% Part (a) Consider an infinitesimal segment of the rod with length dy and located at coordinates (0, y). Enter an expression for the contribution of the charge on this infinitesimal segment to the y component of the electric field at P, the origin, in terms of the linear charge density on the rod, A, variables given in the problem statement, and fundamental physical constants. dEy =- 17( 4 1 60 ) ( ) dy/y=) / Correct! 25% Part (b) Calculate and enter the y component, in newtons per coulomb, of the electric field at point P, the origin.
