- ✓Eddy currents are produced in the conducting frame over which the coil is wound
- BIts magnet is very strong
- CIts pointer is very light
- DIts frame is made of abonite
The pointer of a dead-beat garranometer shouls steady state deflection as eddy-cumments are generated due to the coil coound. This eddy-cumment is due to the coil which is wound and produced in the conducting fuame.

$(a)$ The electric lines of force entering into a Gaussian surface provide negative flux.
$(b)$ A charge ' $q$ ' is placed at the centre of a cube. The flux through all the faces will be the same.
$(c)$ In a uniform electric field net flux through a closed Gaussian surface containing no net charge, is zero.
$(d)$ When electric field is parallel to a Gaussian surface, it provides a finite non-zero flux.
