'X' is a subatomic particle. It has neither `+ve` nor `-ve`. Then 'X' is

Which integer neither +ve nor –ve?

At x=af^(I)(x)=0,f^(II)(a)=0 also f^(III)(a)=0 and f^(IV)=+ve, then (i)f(x) is minima at x=a (i) f(x) is maxima at x=a (iii) f(x) has neither max nor min at x=a (iv) none of these

Velocity -time graph of a particle executing SHM is as shown in fig. Select the ocrrect alternatives. (i) at position 1, displacement of particle may be +ve or-ve (ii) at position 2, displacement of particel is -ve (iii) at position 3, acceleration of particel is+v (iv) at position 4, acceleration of particle is +ve

Draw E-r graph for 0 ltrlt b , if two point charges a & b are located r distance apart , when (i) both are + ve (ii). Both are -ve (iii). A is + ve and b is -ve (iv) a is -ve and b is + ve
