Solution

The correct option is D ,+,+,,+,
To get two times electric than earlier place -ve charge on U.Electric field due to U and R is 2 times than only due to R.Now place 2 positive and 2 negative to cancel each other. Place +ve at P and S and -ve at Q and T or -ve at P as S and =ve at Q and T.So possible arrangement is either +,-,+,+,-,-or -,+,+,-,+,-
