If length of rod X is (2.25±0.02) cm and that of Y is (5.19±0.02)cm, then rod Y is longer then rod X by
(a) (2.94±0.02)
(b) (2.94±0.00)
(c) (2.94±0.04)
(d) of these
Correct option**(c) (2.94±0.04)**
Explanation:
Given length of rod X is Lx = 2.25±0.02and length of rod Y is Ly = 5.19±0.02Rod Y is longer, then rod X by
