S1: Be+2 has higher SRP than other alkaline earth metals.
S2: Be+2 has higher hydration energy and greater △aH (atomisation enthalpy) than other alkaline earth metals.
Both S1 & S2 are true
S1 is true ; S2 is false
S1 is false ; S2 is true
Both S1 & S2 are false
The correct option is(A): Both S1 & S2 are true.
Be has least –ve SRP value because of high △aH (atomisation enthalpy), inspite of maximum hydration energy.
The correct option is (A): Both S1 & S2 are true.
A square loop of sides \( a = 1 \, {m} \) is held normally in front of a point charge \( q = 1 \, {C} \). The flux of the electric field through the shaded region is \( \frac{5}{p} \times \frac{1}{\varepsilon_0} \, {Nm}^2/{C} \), where the value of \( p \) is:
