A galvanometer has `50` division, current per unit deflection is `20 muA` and resistance of coil of galvanometer is `100Omega`. Find the value of resistance `R_(1),R_(2)` and `R_(3)` if its range as a voltmeter when used between `A & P_(1)` is `(0-2V)` between `A` and `P_(2)` is `(0-10V)` and between `A & P_(3)~ is `(0-20V)`
