Consider the following statements
(A) Gravity is always attractive, while electromagnetic force can he attractive or repulsive.
(B) Mass comes only in one variety (there is no negative mass), but charge comes in two varieties : positive and negative charge.
Select the correct options
(a) (A) is false but (B) is true
(b) both (A) and (B) are true
(c) (A) is true but (b) is false
(d) Both (A) and (B) are false
gravitational force between a planet and a body is always attractive but the electro magnetic force is attractive between un like charges and repulsive between like charges.
charges are of two types even though mass is only one type.
