The equation of a circle is given by x 2 + y 2 = a 2 , where a is the radius. If the equation is modified to change the origin other than ( 0 , 0 ) , then find out the correct dimensions of A and B in a new equation : x - A t 2 + y - t B 2 = a 2 The dimensions of t is given as T - 1

A = LT , B = [ L – 1 T – 1 ]

A = [ L – 1 T ] , B = [ LT – 1 ]

A = [ L – 1 T – 1 ] , B = [ LT – 1 ]

A = [ L – 1 T – 1 ] , B = [ LT ]
