Answer:

70

Explanation:

the main equations for finding magnification of a micriscope are:

(1) M=Mo × Me

Mo= magnification of objective

Me= angular magnification of eye peice

(2) M=(Vo/Uo)(D/Fe) for normal adjustment final image at infinity

(3) M=(Vo/Uo)(1+(D/Fe)) for near point adjustment

final image at D=25cm

(4) M= (L/Fo)×(D/Fe) ( normal adjustment )

L=separation or lemgth of microscope

(5) M= (L/Fo)(1+(D/Fe))

here in this question we will be using eqn 4

M=L×D/Fo×Fe = 7×25/5×0.5= 70
