Two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below.
a) Both A and R are true and R is the correct explanation of A
b) Both A and R are true but R is NOT the correct explanation of A
c) A is true but R is false
d) A is false and R is also false
1. Assertion(A) :
In a nonuniform electric field, a dipole will have translatory as well as rotatory motion.
Reason(R):
In a nonuniform electric field, a dipole experiences a force as well as torque.
2. Assertion(A):
Electric field is always normal to equipotential surfaces and along the direction of decreasing order of potential
Reason(R):
Negative gradient of electric potential is electric field.
3 Assertion (A):
A convex mirror cannot form real images.
Reason (R):
Convex mirror converges the parallel rays that are incident on it.
4. Assertion(A):
A convex lens of focal length 30 cm can’t be used as a simple microscope in normal setting.
Reason (R):
For normal setting, the angular magnification of simple microscope is M=\(\frac{D}{f}\)
