Assertion :Three equal charges are situated on a circle of radius r such that they form on equilateral triangle, then the electric field intensity at the centre is zero Reason: The force on unit positive charge at the centre, due to the three equal charges are represented by the three sides of a triangle taken in the same order. Therefore, electric field intensity at centre is zero

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Assertion: The sides of a triangle are 3cm, 4cm and 5cm. Its area is $6 c m^{2}$

Reason: If 2s = (a + b + c), where a, b, c are the sides of a triangle, then area

$= \sqrt{(s - a) (s - b) (s - c)}$
