Question
Consider the following statements and select the correct option which correctly identifies true (T) and false (F).
(i) A charged object can attract something that is uncharged.
(ii) An atom that gains electrons becomes positively charged.
(iii) Charges can be transferred from one body to another.
- (i) (ii) (iii)
T F T
- (i) (ii) (iii)
F T F
- (i) (ii) (iii)
F F T
- (i) (ii) (iii)
T T F
