Answered by kashvi5326

the answer of this question is the ratio of r divided by r dash is equal to 25

sarthak6142: solution pls

kashvi5326: as we know when we have to find out the total resistance we use the formula of 1 by R1 plus 1 by r 2 + 1 by r3 + 1 by r4 + 1 by R 5 according to the total resistance now it is cut into 5 parts then we use Formula 5 by r + 5 by r + 5 by r + 5 by r +5by r then take l.c.m. u get answer 25 r is 1 by r so r is 25 you just have to follow this step first you have to take these steps just ok. it may help you

kashvi5326: when u take l.c.m. u get 25 by r ok sorry for mistake

sarthak6142: that's

sarthak6142: thanks

kashvi5326: ur welcome dear
